I keep trying cars and getting horrible orange peel on them and putting them back in the box. One day I'll get a decent looking gloss finish- one day............
And there is the issue with model cars. Getting the smooth finish.
Maybe Joe can jump in on this with his process. But from what I know-- you need to sand the primer coat (if used), the color coat, and then the clear coat, again, if used. Then polish. There are polishing kits for this that include the sanding cloths. It takes the guesswork out of it and you will end up with glass smooth finishes.
Or --the other way is to lay on a heavy layer of paint to bring out the gloss. But-- you will almost always get something in the paint that will need to be sanded, and then polished.
What says you, Joe?
