I've rattle canned them in the past and within a year the paint is peeling. A little gas or antifreeze and it comes off. I was thinking of DP90 after sand blasting, would that work well? What do you use?

After cleaning/blasting I use epoxy primer and single stage urethane top coat.

I run them through my hot tank and use engine paint.

por 15 semi gloss . its omly as good as the prep my 69 charger has it for 6 years now . just did my 74 charger this spring .

Eastwood extreme black chassis paint...

I used it over a freshly sandblasted one and dries like a rock.

Surface prep is more important than what you use although some of the better paints will last longer.

If you can get it blasted that is best. Check for cracks while the paint is off. Paint it as soon as you can after blasting, and if you handlked it it won't hurt to spray it off with thinner to remove any oily spots.

One thing to remember is that it is possible for oxides to form on the surface without the surface looking orange. They disrupt the adhesion of the paint. So time is critical.

DP90 is awesome stuff, just clean it well. Then topcoat it with some Deltron black. No more peeling when gas hits it.

I'm having one reinforced, welded up and chem dipped, then going to get powder coated. probably overkill, but I like to powerwash stuff and that helps to clean up a bit easier (plus my friend offered to do it for free ).

That's a good idea but rock chips may be harder to fix. Anyone remember Imron? It was developed for truck chassis. Hard to touch up, although I can recall when it was THE paint for show cars.

Bed liner?

Does Eastwood (or anyone else) have a good chassis spray in any other color? Want to do some wheels in red

dip it because it will make it very hard to clean out all the acid

Chemical dip and "acid" are two different things. Hot tanking is not an issue.

imo, either method is going to leave it very bare inside, kinda hard to coat inside and where the 2 halfs are welded togeather. It's gonna rust there when it get's wet.

Blasting the outside you really don't disturb much inside.

I do steam clean the whole thing inside and out before blasting them. So there's no grease inside. Cheap and fast, works good for me. It's a K member...
