I’m painting the Porsche body right now. I have on it the second “wet coat” and tried to sand it to glass using the detail master kit (2400-12,000). However, some of the sides got a bit dinged int he process, and one side is lighter in color than the other. Also there are still some…“pits” I think I would call them, in the paint. Obviously I need to put on another coat, but when? Should I sand out every pit? Or should I just paint as is? Or do I apply a polish right now to smooth out the “pits”? Also is it safe to put on decals after you wax? or will the decals have a hard time adhering to the finish? (That seems to make sense to me). Thanks guys!
I would sand down the imperfections and spray again 'til I was satisfied with the results. What ever you do don’t use any rubbing compound until you are sure that you don’t have to put on any more paint as this can cause fish-eyes in the paint due to some ressidue that the compound leaves on the paint. Hmmm…those pits your talking about sounds like fish-eyes to me. Is it tiny spots that repells the paint? In that case you have some contamination on the body that will keep ruining your paint job. With a little luck you can do a spot sanding and if you’re using a solid colour put in a drop in each of the fish-eyes and sand smooth before putting on a final wet coat or two.
I think wax is best put on after the decals for the same reason you stated.
Good luck!

Thanks Niclas, that is what I thought but wanted to make sure before I went any further. I think the finish is more of an orange peel effect, becuase the paint never seperated when I sprayed it on. And by sanding the high spots, it has made it look like little pits for lack of a better term…lol I’m gonna finish making the body look like glass, and then spray another wet coat tonight…thanks again!
Before you apply any more paint clean the body with rubbing alchohol. This will remove any oil fron your fingers and/or mold release. Fisheyes are generally caused by some sort of oil that the paint will not adhere to, including finger prints. The paint draws away from that spot.
When the body is clean sand it smooth, that is the paint you already have on the body. Clean it again and do not touch the surface you are going to paint. Apply additional coats as necessary to finish the model. If it is a solid color, that is non metalic, you may be able to touch up the spots as necessary.
If you are using an enamel let it dry for a few weeks before you use the finishing kit. Enamel stays soft for a long time.
