Durable finish for frame?

I purchased the all awesome por-15 to spray my frame with, but after reading a few posts on here i have come to realize not so many people like it and refer to it as a marketing success. Sooooooo long story short i'm just going to blast it, shoot two coats of epoxy, couple coats of black base then clear it. Sound good to you guys? I'm not going for show quality at all but would want the protection more so then anything. And after i blast it do i need to sand the bare steel or is the sandblasted surface a better tooth for the epoxy to bite into? Also I'm going to blast all of my door jambs, can i just go straight to epoxy without hand sanding all of that? thank you

a QUALITY single stage will do well on the frame. BC/CC on the frame... while it looks great on a trailer queen, it never worked out to well from what I've seen on a street car

If you are truly sand blasting then YES I would say you'll need to knock the texture down some on the jambs, maybe not, depends on how its done

Go with the epoxy, but save yourself some extra work and cash and go with a quality single stage gloss. Do not let anyone talk you into using Imron, it ain't what it used to be.

Aright epoxy it is, but why won't the BC/CC system work as well as a single stage would?? I have a ppg jobber not far from me, should I get it from them? And what brand?

I used SPI black epoxy primer and left it that way. It's a nice semi-gloss finish that doesn't need top coating if not exposed to UV.

I did 2 coats. The first one in gray and the second in black. I did it that way in order to make it easier to get a good even coat on the second coat. If both coats are done in the same color, it's hard to know on the second coat where you sprayed while trying to get all the angles.


Frame blasting 3/4 complete:


After first coat (SPI Gray Epoxy):


After 2nd coat (SPI Black Epoxy):


Frame, springs, A-arms and calipers are all done in black SPI epoxy:

The black SPI epoxy is a durable and economical alternative to other methods, and has the advantage of being a one-step process with excellent corrosion and chemical resistance. It's a no-brainer, really.

Yes and if one needs to fix something it is easily repairable..
