Morning all.
Well I've been having a nightmare with this. The body had been painted, glossed and polished some time ago but I still had to paint the chrome window trim. I masked everything up, and then in a stupid moment decided to use a paint pen for the chrome instead of airbrushing. This went disastrously with the chrome paint bleeding under the masking tape.
I tried to remove it with thinners and sanding, but of course this just made things worse. Luckily I had only done one side so decided just to respray the top of the door and edge of the roof that were damaged, so masked up this area. This left a paint ridge along the roof which I thought I could sand out. I was wrong, leading to more masking and the entire roof needing to be sprayed, glossed and polished again. Having done this I found some dust stuck in the boot (trunk) lid, and while trying to polish this out I got to close too the edge of the rear wing (which is very square) and rubbed through to primer. This then had to be sprayed again, which I did without masking to avoid the same issues I had with the roof.
So 3 weeks later I was back to square one and ready to paint the chrome trim again. I masked up again and did what I should of in the first place and airbrushed.
I still need to polish the body again but will wait a few days to make sure the chrome is fully cured. I really don't want to have to mask it all up again.
So lesson learned, don't try and cut corners.
