I've just purchased PaintScratch's touch-up pen (primer, paint and clear coat) and will soon be addressing a few blemishes on my car.  I have two varietes of spots:

  • Small stone chips about 1/16" or less.  I can catch my finger nail on them and the exposed coloration below is whiteish.  I am assuming that the clear coat is corrupted and I will need to prime, pain and clear coat. 

  • The other spot is an area that was probably scratched by a car key, I don't know.  The scratch was about 3 inches long and varied in depth.  I was able to manually remove 80% of the scratch with Maguiar's fine cut polish.  After several attempts, I graduated to a medium cut polish.  I applied this maually (finger tip) as with the fine cut.  In retrospect, this probably was not the best thing to do because now the remaining 20% of the scratch has flattened out and widened.  The spot is about 1/2" long and 1/4" or less wide.  It is colored whiteish or grayish.

I'm not sure what I am looking at when I see the white/gray.

My questions ---

What is the likely condition of the clear coat for both of these? 

Is ther a way, a standard test, to tell if the clear coat has been damaged? 

Is there a way to tell if there is a base coat of paint beneath the whiteish/grayish spots?

Does a chip tell me that I definitely need to repaint?

I'm asking these because of the way clear coats have been described - or the way I understand them.  For instance, a scratch in the clear coat apparently disrupts its mirroring (shine) so that the human eye sees a "white" scratch instead of the paint below. 

Thanks for any help you have.

Most often if the clearcoat is damaged it is best to also repaint the underlying basecoat.
