How should I paint my radiator core support? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

My core support is epoxy primed. I think I am supposed to rough that up a bit with sandpaper before painting.

A friend suggested implement paint from Tractor Supply but I'd have to buy a spray gun. I know Harbor Freight has a cheap and decent one but can I get by with spray paint?

If I can, what spray paint is best? Will plain gloss black work or need I get some sort of engine enamel?

If you want to be more original use an engine enamel that is semi flat or you can use gloss. Implement paint does not hold up as good as a quality engine enamel.

If you wanted a more semi gloss type color go to the nearest John Deere store and buy some Blitz Black. It can be had in spray cans and looks pretty darn cool. Jim

What I've been using on my parts lately is the rustoleum (professional) high performance enamel. Gloss black in tall can. Not the same stuff as the cheaper , smaller cans. All stores around me carry it including my local wal-mart but it is about $7 a can. It's held up as good as my frame I sprayed with gun and lays just as nicely. I can't tell the difference but I did sandblast and primed before painting as well.

What epoxy primer and color did you use?

I had it primed at a media blasting shop so I don't know. It's black epoxy primer though.

I'm using the SPI

Sorry pulled the trigger too quick....I'm using the SPI epoxy primer for the prime and finish coats. It is uv protected and is easy to shoot.

The Southern Polyurethanes epoxy primer ends up as a satin/semi gloss finish not flat but not too shiny if you know what I mean. In my experience it takes weeks before it is fully cured to final hardness based upon my experience.

I used rustoleum etching primer then the professional enamel. The reason I went with it for my truck parts is because how well it's held up on a utility trailer I built from an old boat trailer. I'm very pleased so far...
