I have removed the plastic nose cone and rear license plate area on my 1996 Miata in order to paint them.

I have sanded progressively to 400 grit. I do not plan to prime these parts. My questions are:


Should I sand to a finer grit for adhesion?

How long do I wait between coats to sand? and when I do, what grit do I use and should it be wet or dry?

Is sanding necessary between final coat and clear coat?

Thanks

If you don't use primer before you paint the parts then the paint won't look that good. If you expect a good high gloss shine to it then always prime before painting. Wet sanding after final coat is a good idea it helps remove any contaminants in the paint and orange peel to give it the best look.

I have painted the plastic nose and tail of my Miata with acceptable results. How long should the paint cure b4 wet sanding, and what grits should i use?

24 hrs....ans use 1500 wet and then buff
