OK, once more if I didn’t say it already. You cannot just spray clear over the color coat if it is peeling. It will never match. Base coat/clear coat needs to be done in two parts. The color coat then in a specified time frame the clear is put on. Base is dull and once the clear is on has a slightly different color.
Now the Dupli-color stuff is more of a single stage color coat but you can also spray clear over it so it is not the same as the factory base/clear. At any rate if you are missing clear on a factory job, you need to paint over it with color, then over coating it with clear is optional.
The clear on the roof on my Park Ave was peeling in a pretty large area. I was going to sell the car, had clear on hand, and didn’t want to pay the $80 plus for a pint of color. So I just re-cleared the top. It was nice and shiny from the side, and protected the roof, but the color was all off if you looked at it from the top. I wasn’t about to re-do it again but just saying if your clear is peeling, don’t think you can just spray more clear on it.
