LC CCS White pad/black paint before and after use ???

[gibson24]

Two weeks ago I did full paint correction on black 2015 GMC 3500. I started with M105 with a Orange CCS pad then moved on to a white CCS pad with 205. Standard procedure...

Yesterday I did a polish only with M205 on a black 2004 Jaguar XJ8. Just after a few panels the surface of the white pad was turning black in a hurry. When I did the GMC that was also black in color the white CCS pad stayed basically clean appearing for the entire project.

I'm wondering why such a difference occurred. I posted pics of both jobs in another thread although I'll post a pic of the white CCS pad after the use on the Jaguar. The pad was actually twice as black as what the picture shows because I had cleaned the pad off with a towel and it's just been in a bucket with cleaner.

Let me know what you think.

Also, at first I did a test spot with M105 and a CCS Orange pad and that also was very unlike the 2015 GMC. After a small test spot the 105 was very difficult to remove with a microfiber. On the GMC I had no issues applying or removing the 105. Almost like removing a dried wax on the Jag. May have no relation just thought that was strange. I'm still learning here...

Is it single stage paint? The car could have been repainted in just an area with single stage paint.

[gibson24]

My first thought was a re paint... I also mentioned to the owner the vehicle may have been repainted but he was unaware of work done to the car. He bought it last year privately but didn't have any history of the car

[gibson24]

I couldn't visually find of a possible repaint though on the car anywhere. That doesn't mean an expert wouldn't have though.

Maybe road film?

What year is the car? You can get the paint code and contact an auto paint retailer and they can tell you if it's single stage. Looking at that pad I would say it is single stage.

I've seen people polish a car with a white pad without claying...I'm pretty sure that's black paint on those pads.

2004 Jaguar XJ8 Vanden Plas.

I did wash and clay the vehicle thoroughly prior to starting paint correction. I use Griots clay and Speed Shine. Wash/clay is my standard procedure just to put that out there.

I will get the vin code an do some research for sure. That's a great idea.

[gibson24]

Just did a quick Google search. The paint did not have metallic so the code may be "1807, pce"

Just read Mike Phillips write up on single stage vs clear coat. Definitely sounds like a single stage paint issue on the white pads....but on a 2004 Jaguar? Strange

Do you have a paint thickness gauge? It is very easy to tell if a panel has been repainted based on the thicker film build on re-sprayed panels.

[gibson24]

I do not. After this last job I been seriously thinking about getting a gauge. Any recommendations on a quality gauge that won't break the break? I do this as a side job

Back in 2003 or 2004 when I purchased my 1st PC, I owned a black 2000 Dodge conversion van. Every time I polished the paint, my pads turned black. The first time it happened, I thought what the hell, single stage paint on a 2000 van???? But, the paint was BC/CC and I just blew it off as contamination....
