Interesting idea Roe. I know what you mean now, build it up, feather it in then coat the whole panel.

At first I wasn't that worried about it since I would just have to repaint a single door, or the rear trunk shelf.. but now I have about 6 spots like that, and using what you suggested could definately save me some time.

In fact even in areas that have the original 8 coats on it that have dark colors, I could probably try that there too. I think what I'll do is another 3 coats over the whole car, then if the bulk of the car is colored well, I can try what you suggested on the spots that show through, then do the whole car with 2 more coats when those freshly fixed parts are colored.
