You use the POR system which has it's own primer that stops rust from occurring. The epoxy coting in exceedingly durable, but pricy. An alternative is simple Rustoleun over a high zinc primer.

Mine is going to get two coats of epoxy primer with four or five coats of black semi gloss single stage urethane paint. Would love to have it powder coated, but because of price and location that's not going to happen.

I'm sure this reply will draw ire, BUT, every instance of POR15 (which stands for PAINT OVER RUST) on clean, bare steel I've personally seen, FAILS to adhere and peels over time. It simply doesn't seem to stick unless there is some rust present, which is what it was originally designed to do. I've also witnessed people applying multiple coats and it doesn't stick to itself either and will peel. It does better if it is sanded between coats, but what is the point of that ? may as well paint over it. POR15 is an excellent rust CONVERTER but if you've removed the rust there is no longer a need for a converter.

My preference for a blasted frame is powder coating. If that isn't an alternative, then an epoxy sealer/paint is next.

1947 Ford street rod frame going to powder coating.





All the suspension pieces went too. If I remember correctly, it cost around $700 for blasting and coating.



I love the glossy look and durability.

Thanks all.. I would love to have the frame powder coated, but unfortunately that's not an option right now. For now i'll go with epoxy primer and urethane paint. Thanks again!

Depending upon finances, I would probably do the epoxy primer, like "DP-90" if I could.
You can spray that with a cheap $20 harbor freight paint gun, outside, on a quiet morning.
Zero-Rust is a good option as well, like you mentioned.

Lacking funds - There's nothing wrong with Daves suggestion of a high zinc primer and a spray can top coat. Eastwood has a nice "chassis black" in spray cans.

NO NO it wasn't ,I sprayed it down with some prep and etch I found at home depot .Put some in a spray bottle full strength psray it on and let it sit for half a day, then power wash it off. I did this twice came out CLEAN plus it gave an etch for paint to adhere. I also pour some into a can and let my bolts soak or whatever and it knocks the rust right off. You need to rinse and dry asap or it will flash rust. A gallon of this stuff was like $12 or so bucks. Don't be an idiot this stuff is basically an acid proper protection is a must After this step I wiped it down with a wax grease remover then sprayed it

I used self-etching primer and then 2 coats of Rustoleum satin black. Just did a frame last month but the ones I did 12 years ago are still perfect. Don S

Thanks for all the info.. I've decided to go with Eastwoods 2k epoxy primer and Chassis black. Inexpensive and should do the job just fine.. Thanks!
