[QUOTE=RussZS;3184257]I’ve just been lucky enough to spend three days down at KDS Keltec with Kelly and his team, learning how to wet sand with the main aim of removing orange peel. Uniquely, this training was concluded on my very own car – a Golf GTI Edition 30 – with the aim of removing as much of the orange peel in my clearcoat as possible.

This thread shares my thoughts and experiences on the time spent with Kelly, and gives an overview from the perspective of a trainee on KDS’s course.

I ** also very fortunate to be the first - I have Certificate 0001!!

Day One :

It’s not very often I get out of bed at 5am, but I needed to be at KDS for 9am for my wet sanding training, so like an excited child on Christmas morning, I was up bright and early and set on my way. I’d forgotten just how bad the M1 and M25 were and unfortunately arrived 15 minutes late!

Upon arrival at KDS’s unit in Gillingham, Kent:

With introductions out of the way (Kelly has a team of 4 including himself), Kelly began to prepare a bonnet which would be the test panel for the first days worth of tuition:


DSC01422 by RussZS, on Flickr

The aim of the first day was to cover the following areas:
- Use of a Laser Pointer to create a fixed point to assess clearcoat removal rates
- How to use a PDG effectively, including how to calibrate one correctly
- The differences between using a DA Sander, working by bare hand and using a block
- Risks around scorelines, pigtailing and dirt/grit
- Using compounds and polishes to remove sanding marks and restoring the gloss to the paint

The test panel itself was absolutely ideal – covered in dents, RDS’s and crucially orange peel:

DSC01428 by RussZS, on Flickr


DSC01432 by RussZS, on Flickr

It’s almost as bad as a new BMW!!:lol:

Here are some pics of the tools we used during the first day:


DSC01435 by RussZS, on Flickr


DSC01436 by RussZS, on Flickr

So we have:
- PosiTector 6000
- Mirka DA Sanders and Abralon Discs
- 3M 1200, 1500 and 2000 grade sand paper
- Meguiars 2500, 3000 and 4000 grade sand paper
- Sanding Blocks

We set up the laser pointer on a tripod, secured by clay, to create a fixed point to allow us to as accurately as possible assess the removal rate of whatever we were doing.
Next Kelly showed me how to correctly calibrate the PosiTector 6000:


DSC01448 by RussZS, on Flickr

A bare metal block was used to create a reference point:


DSC01453 by RussZS, on Flickr


DSC01454 by RussZS, on Flickr


DSC01455 by RussZS, on Flickr


DSC01463 by RussZS, on Flickr

Next we tested with a shim:


DSC01467 by RussZS, on Flickr


DSC01468 by RussZS, on Flickr

That’s pretty close…

Now on a 125 shim:


DSC01484 by RussZS, on Flickr

With the P6000 appropriately calibrated, Kelly moved on to begin the wet sanding demonstration. The key thing I have learnt about wet sanding is how important cleanliness is. If you catch a single dirt particle between the paper and the panel, the consequences can be severe. We began by flooding the panel, to remove any traces of dirt or dust:


DSC01499 by RussZS, on Flickr

We began with 1500 grit. The paper was put into a bucket with warm water and hand wash (to help with lubricity):


DSC01502 by RussZS, on Flickr

Kelly began wet sanding by hand with 3M 1500


DSC01500 by RussZS, on Flickr


DSC01504 by RussZS, on Flickr

To deomstrate just how fine the ‘scratches’ from 1500 are, Kelly went over a test section with Lime Prime and Super Natural Hybrid:


DSC01514 by RussZS, on Flickr


DSC01516 by RussZS, on Flickr



DSC01519 by RussZS, on Flickr

Impressive stuff!! However, up close…


DSC01522 by RussZS, on Flickr

It just goes to show how deceiving some photos could be…

Next Kelly showed me how to use a Mirka DA Sander with 2000 grade disc:


DSC01528 by RussZS, on Flickr


DSC01535 by RussZS, on Flickr

Now from certain angles, it would appear that the orange peel has been fully removed. I’ve seen a couple of threads where this process has been used, and from certain angles it looks perfectly flat:


DSC01533 by RussZS, on Flickr

However up close, at the right angle we can see the peel is still very much there!!


DSC01530 by RussZS, on Flickr

I then had my first go! 4000 Grit Abralon Pad on the Mirka, to refine the finish of the 2000:


DSC01542 by RussZS, on Flickr


DSC01541 by RussZS, on Flickr

I was keen to try the 2000 myself to see if orange peel could be removed on a different part of the test panel:


DSC01548 by RussZS, on Flickr

However again, from certain angles it looks great – very flat:


DSC01551 by RussZS, on Flickr

However, catch the lighting correctly and we can see the peel is still present:


DSC01552 by RussZS, on Flickr

Meanwhile Kelly just off refining the other part of the test panel so that it was all at 4000 grit level:


DSC01560 by RussZS, on Flickr

For fun, we tried P1 via a 4000 Grit Pad…


DSC01562 by RussZS, on Flickr


DSC01565 by RussZS, on Flickr


DSC01569 by RussZS, on Flickr

[FaBeRgE]

Not bad!!

However, clearly not perfect… so next Kelly polished the panel up with Scholl S3 and a Scholl Wool Pad via Flex Rotary:


DSC01573 by RussZS, on Flickr


DSC01576 by RussZS, on Flickr

So the top half of his section of the panel was all done by machine (2000 then 4000 as I’ve seen on here many times) and the bottom part was all done by hand 1500, 2000, 2500, 3000 and 4000 (done properly IMO!).

Using a PDR light, we can see the bottom half of the panel (done by hand)


DSC01584 by RussZS, on Flickr

(Note the dent)

Now the top half, done by machine:


DSC01586 by RussZS, on Flickr

Now we can see that the orange peel has been flattened to an extent, but has not been removed entirely. From my perspective, it was clear to see that sanding by machine was not only very quick but also very easy to do – easier than correcting paint with a rotary certainly! Whilst it did flatten a little, it was beginning to become clear that to remove orange peel correctly and fully, then it needed to be done by hand.
Further pics of the panel:

Top Half (machine)


DSC01590 by RussZS, on Flickr

Low Half (hand)


DSC01593 by RussZS, on Flickr

Then it was my turn….!!!

So, before I started, we took a paint reading:


DSC01597 by RussZS, on Flickr

I started, like Kelly did, with 1500 grit:


DSC01601 by RussZS, on Flickr


DSC01600 by RussZS, on Flickr


DSC01599 by RussZS, on Flickr

Very scary stuff at first! It needed another pass to completely flatten the remaining peel:



DSC01603 by RussZS, on Flickr


DSC01605 by RussZS, on Flickr

Much better… much more even coverage and crucially, the peel is all but removed:


DSC01606 by RussZS, on Flickr

2000 grade was next, then 2500:


DSC01608 by RussZS, on Flickr


DSC01609 by RussZS, on Flickr

You can see the gloss starting to return to the paint at this stage, it becomes far more reflective.


DSC01611 by RussZS, on Flickr

We finished with 3000:


DSC01613 by RussZS, on Flickr


DSC01612 by RussZS, on Flickr

Next I used the Flex/S3/Wool combination to remove the sanding marks:

[FaBeRgE]

[QUOTE=RussZS;3184258]That was my first practice run, so now we would repeat the process but on the fixed point where the laser pointer is:

First the panel was flooded:


DSC01621 by RussZS, on Flickr


DSC01622 by RussZS, on Flickr


DSC01623 by RussZS, on Flickr


DSC01626 by RussZS, on Flickr

This is after 2 passes with 1500


DSC01634 by RussZS, on Flickr


DSC01638 by RussZS, on Flickr

2000 next:


DSC01639 by RussZS, on Flickr


DSC01643 by RussZS, on Flickr


DSC01645 by RussZS, on Flickr

Then on to 2500:


DSC01646 by RussZS, on Flickr


DSC01647 by RussZS, on Flickr


DSC01651 by RussZS, on Flickr

After 3000 we can really see the gloss starting to return, you also begin to get an appreciation of the final finish you are going to achieve:


DSC01656 by RussZS, on Flickr


DSC01652 by RussZS, on Flickr

So, to summarise, at this stage I had hit the panel with 1500 twice, 2000, 2500 and 3000. We have seen the clearcoat reduce from 134-136 range, down to 128, to a maximum removal of about 6-8 microns. However, we must remember that this paint is rather quite soft, as the next test so aptly demonstrates.
Now it was time to remove the sanding marks, which were very fine, with a machine polisher. To try something different, I suggested we tested this with the Megs MF system (cutting disc and D300) and a Megs G220 DA:


DSC01657 by RussZS, on Flickr


DSC01658 by RussZS, on Flickr


DSC01660 by RussZS, on Flickr


DSC01661 by RussZS, on Flickr

I was expecting this, after all of this wet sanding, to remove about 2 microns or so, however we were both very surprised by this…

DSC01662 by RussZS, on Flickr

So we’d taken off 6-8 from all of that wet sanding, then the same again use the Megs MF system!! I was very surprised by the rate of removal. I worked the panel for 2-3 passes… as recommended.
Next, to test how much we would have removed had we used a Rotary, Wool, S3 and the right technique:


DSC01665 by RussZS, on Flickr

This took it down to 122:


DSC01664 by RussZS, on Flickr

Next Kelly refined with Scholl Orange Spider Pad and S17+:


DSC01669 by RussZS, on Flickr


DSC01668 by RussZS, on Flickr

Then a further set with 3M Yellow Pad and a mix of 3M UltraFina and Extra Fine Compound, to leave:


DSC01672 by RussZS, on Flickr


DSC01673 by RussZS, on Flickr

Final reading of:


DSC01676 by RussZS, on Flickr

This was the end of Day One. I was staggered by the difference in the clarity of the panel, especially given that I’d done it largely myself! The removal rate of the Megs MF system was a bit of an eye opener for me too – I’ve only tended to use it on harder cars, removing around 3 microns. I’m going to do some further testing on softer paints to see if what we saw here is consistent. The effectiveness of wool surprised me too, and also how very little is actually being removed by the wet sanding process (especially when compared to the MF system). That was a long, but rewarding 12 hours…

Day Two:

Today we would be starting on my Golf! I was feeling quietly confident after doing a good job on the test panel – but as I’d soon discover, it’s a lot trickier working on a car with curved panels, when compared to a nice flat bonnet!
My car was shockingly filthy, so would obviously need a thorough cleaning before progressing. Paul, one of Kelly’s team very kindly cleaned the Golf for me, whilst Kelly let me have a play with the smaller Mirka sander and looking at RDS removal.
Letting Paul clean my car was a very odd experience for me as I’d not let anyone near my car for the past 5 years. However, as he was one of Kelly’s guys, I’m sure it’d be cared for in the highest possible way!


DSC01677 by RussZS, on Flickr


DSC01678 by RussZS, on Flickr


DSC01679 by RussZS, on Flickr

What a shocking state – hardly the best rolling advertisement for me!!:lol:


DSC01686 by RussZS, on Flickr

Back inside, Kelly was busy with his blade creating a load of RDS’s for me to remove!


DSC01689 by RussZS, on Flickr

I’ve seen lots of threads where a Mirka and Sanding discs are used to remove an RDS, so Kelly was keen for me to have a go at this to see how effective this process would be:


DSC01694 by RussZS, on Flickr


DSC01695 by RussZS, on Flickr

2000 disc:


DSC01698 by RussZS, on Flickr

It soon became very evident that wet sanding by machine, due to the firmness of the discs used, was levelling the paint (as expected) and therefore was not very effective at rounding any scratches off. The other point here is that you would be flattening the orange peel to an extent too, so this could look very odd on a very ‘peely’ surface.
On the taped off area, Kelly showed me how effective a rotary is at rounding RDS’s:


DSC01722 by RussZS, on Flickr


DSC01724 by RussZS, on Flickr

Really edging the pad to get the rouding to be as effective as possible:


DSC01725 by RussZS, on Flickr

The scratches were beginning to disappear, but so was the clearcoat!!


DSC01742 by RussZS, on Flickr

Still they were not quite gone, so more cutting with the Orange SP and S3:


DSC01743 by RussZS, on Flickr

He was REALLY working the panel too:

DSC01746 by RussZS, on Flickr


DSC01750 by RussZS, on Flickr


DSC01749 by RussZS, on Flickr

What became clear at this point was that sanding wasn’t removing nearly as much clearcoat as I perhaps perceived, and that a lot of us have removed far more removing an RDS (clearly these were very severe examples though!)
We took a couple more pics of the panel and then turned our attention to the Golf:


DSC01796 by RussZS, on Flickr

Please note that’s a bare panel, no CG Kore


DSC01797 by RussZS, on Flickr


DSC01800 by RussZS, on Flickr

Now it was time for this:


DSC01801 by RussZS, on Flickr


DSC01802 by RussZS, on Flickr

It looks well from a distance, but up close…

DSC01817 by RussZS, on Flickr


DSC01818 by RussZS, on Flickr


DSC01820 by RussZS, on Flickr


DSC01819 by RussZS, on Flickr

Again, we calibrated the PosiTector 6000:


DSC01824 by RussZS, on Flickr

It was out by a fair bit..so it was calibrated:


DSC01825 by RussZS, on Flickr

Test on the blue Shim (should be 125)

A few more pics of my peel using a PDR light:


DSC01841 by RussZS, on Flickr


DSC01842 by RussZS, on Flickr


DSC01845 by RussZS, on Flickr

We also taped up all panel gaps and put a protective sheet over my engine bay. I’d not considered this previously, but it was to stop the water, which would contain clearcoat, from drying and hardening in my panel gaps!

What an amazing three days. I’d like to express my deepest and sincerest thanks to Kelly and his team (Paul, Cons and Tracey) for their wonderful hospitality and time. They are a great bunch. I also have been astounded by Kelly’s detailing skills and knowledge of paint and all things detailing. He really is up there with the very best. I’ve never seen anyone handle a rotary with such skill and fluidity. I consider myself to be very good, but he has shown I can still learn more in terms of correcting more effectively in a shorter space of time – I’m going back for a bit more tuition next year. I’ve seen a lot of people polish, but nobody quite like this, and I need to learn in this way too.
My car looks incredible, and it’s so very rewarding knowing that I have done a lot of it myself. I could have never got it to look this good with a rotary alone. Swirl removal and jewelling can only take a finish so far. The increase in reflectivity and clarity you get from removing the orange peel is nothing short of breathtaking and I’d recommend it to anyone. I think the key point to remember is that on my car, we were removing as little as 6-8 microns to achieve this finish. The Megs MF system took off just as many just removing the 4000 grit marks, and we took off 15-20 removing an RDS – these are things detailers are doing every day all over the world. Wet sanding isn’t nearly as scary as it looks. Clearly it won’t be for everybody and won’t be suitable for every car, but we should remember that we are only removing the ‘high points’ in the clearcoat and making it perfectly flat. Very little of the ‘base’ is actually removed at all.

I’d also like to say thank you to Roy – without Roy we would have struggled to finish it in time, and I’d still have a very swirly roof. Thanks as ever Roy, a true Gent.
If you managed to read it all – then thank you. I know I will have missed some key points and would be happy to answer any questions where I can. Kelly will also be doing a thread from his own perspective (and with more more professional photos lol!)

This is the money shot for me!
