~One man’s opinion / observations ~
The question was also asked if clear touch-up should be used as a final coat to repair chips on clear coat paint. There are two viewpoints to this question. The purist will say yes, the paint has a clear coat and thus, the repair should also. The process is the same as previously described, except the clear coat is substituted for the last 2-3 coats or paint. The practical world says no. The touch-up paint is different from the original paint and is formulated only as a touch-up paint. Once it is applied it should, according to the manufacturer, match well enough to be all but invisible. I have found this to be the case with the numerous repairs on the many cars/colours, I have completed. If you are using the original paint as a touch-up (I have not done this with a clear coated car), then my understanding is that you should use the clear as a topcoat. The colour coat of some paints will many times be relatively dull in appearance. These paints rely on the clear coat to provide the "shine." Try one chip in an area that is not that visible. If the process works, then continue with the rest. If not try the clear coat top layer.
