Do you have a compressor and a spray gun? Semi-gloss black in an epoxy or urethane is a durable finish.
i`m just looking to see what brand people are using or used and hows it holding up? i`m using eastwoods 2k chassis black with ceramic (semi) on my fame but i shot etching primer on the car and eastwood says to put that paint over 2k epoxy. and i know i can sand the etch primer off but i dont want to sand any more then i have to,soooo i`m looking at all my opptions before i jump in to all that sanding. i hit the car with etching primer because i had it and i needed to cover the car with somthing so i can get the welding done. the rest of the body i will be sanding it off (etching primer) after the metal work is done. but for the fire wall and under side i`m thinking of going down a different road .
You should be able to just scuff the self etching primer with scotchbrite and lay some epoxy primer over it. Epoxy is generally a good sealer. Read the product info sheets to be sure it's compatible. What brand of etch primer is it?
I am a big fan of the zero-rust paint. You can buy it in rattle can or quart, it is direct to metal paint and claims to be as corrosion resistant as por15 but much less a pain to use. I use the black for all under car and suspension parts and it goes on as a semi dull black finish. Not as shiny as a semi gloss but I really like the look of it. I am also using the white on the interior floors to lighten up inside to make it easier to work in there and see things. As to durability I can't say because my car is in pieces inside but it seems to be a good paint to me. Time will tell of course.
Korrie, I do not think the GM recon paint is very durable. It is lacquer based. Not good for the bottom of a car for long term.
