Has anyone used Gm restoration enamel paint that is ready to spray right out of the can? I was thinking about spraying my rearend,radiator support, inner fenders,firewall and maybe underneath my car with it.Any opinions about durability and what you guy's think about it. THANKS!

I used some of it, frankly it sucks. It is very soft, wipes away with gasoline and you are basically paying for paint that is already reduced. I would reccommend Rust-Olem Semi-Gloss black that you can purchase at Home Depot. It is a much more durable finish and the color very close to original.

So how does Eastwoods chassis black compare to either of these paints?

In my opinion eastwood chassic black is too glossy for an original finish.

Eastwood chassis black & under hood black are both too glossy . Going through the same thing right now also . The color that comes the most close is Quanta's #4 semi-flat black ( had some left over from a previous resto but not enough of course ) but i see on there web site they are not advertising it , have all others , 1 through 5 but no 4 . Go figure !
