Title: Lacquer/Enamel paint
Post by: Matto on June 19, 2011, 10:30:55 AM: I am cleaning up a CJ3B to use as a weekend driver while my 3A is apart. (thought I could finish the 3A project in a year. RIGHT.) ï¿½The original color was Granada green metallic. I am planning to use Duplicolor Paint Shop Emerald green metallic lacquer. Over the years this jeep was painted red with enamel based spray paint. You can spray enamel over lacquer but you can't spray lacquer over enamel.
Duplicolors website says you need to spray an apropriate sealer on the enamel paint before applying lacquer but they do not say where to get the "sealer". Has anyone used something like this? I don't want to strip the entire jeep, it's not a 100 point show piece. And I'm not sure if the factory paint is lacquer or enamel either.
Thanks
Matt

Stick with an acrylic enamel if possible. You really do not want to wet sand and buff out a jeep. Besides, Lacquer is not a durable paint anyhow. ï¿½If you are worried about spraying the metallic , you could go with a basecoat clearcoat as teh basecoats are very similar to lacquer to spray, while the clear can be enamel like or even urethane...

In many places you can't even buy laquer based auto body finishes for VOC compliance reasons.

This might ï¿½also be a great project for you to prep and MAACO to paint. You get pro sprayers, and you do all the tedious fine work like masking and part removal..

You also might want to try a high pressure car wash on that grille..It may strip it right down to the factory green, which was enamel based to my understanding.

I will hit everything I can with a DA, I was more concerned about body joints, inside corners, and nooks and crannys. I will switch to enamel paint. I guess there's no easy way around proper prep.
