Painting

[Doug D.]

so i purchased some humvee doors from Western Kentucky Surplus. They are the fiberglass ones and are pretty nice. Wanted to know how to prep to paint them.
I am using Rapco paints and need to know if i need primer. Do i need to sand them? What grit sandpaper?

Have you contacted West Kentucky Surplus to see what they recommend?

yea i have but not sure i like it. they use liquid sandpaper and then prime it. Never used that before and also don't know what type primer to use.

liquid sandpaper is just a chemical alternative to sanding, to remove the gloss layer on the set resin to allow primer to bond to the fiberglass better.
I see no reason why you can't treat it like any other fiberglass paint prep if that is all they do.
Then just use a primer rated for fiberglass.

If it's totally unpainted, then clean it up with a degreaser, scuff it with 220-240 grit sandpaper until all the gloss appearance is completely gone, and wash it down again.

Coug is absolutely correct (as always).

There is also a paint and restoration section on SteelSoldiers. It has members who might have done similar stuff

I only get to be correct since I'm single. I spent a few years never being right, and decided to fix that problem.
