The last two I've done bare frame. One blasted, Eastwood rust encapsulator(doubles as primer) then Chassis Black. The second, I wire wheeled, Ospho to kill any remaining rust, then encapsulator, then Chassis Black. Both turned out well and holding up no problems. Frame off I've spayed, if I did it on the truck, I'd probably use POR-15 and brush. Nasty stuff if you get it on anything(especially skin), and not UV protected unless topcoated.

 

Good points about the powder coating. I figured i'm in so Cal, rust isn't really an issue here, my trucks pretty free of it. Best bet is to not skimp though, clean it well and make sure it's sealed up

 

I did my 75 Monte Carlo frame with Chassis Black and wasn't impressed. It just seems like it isn't thick enough. For my 78 Scab, I blasted the frame, couple coats of Epoxy Primer followed by a couple coats of Black Tractor Enamel from the tractor supply store. I definitely like how it came out much better than the chassis black. here's my build: https://www.ford-trucks.com/forums/1...y-78-scab.html

 

first I sandblasted the whole frame taking off what ever I could to sandblast and paint separate, than I used KBS Coatings 3 step system. Which includes a degreaser/cleaner as step 1, than a Rust remover, than the paint which is really tough and comparable to POR15. Even though I sandblasted the whole frame to bare metal I still did all 3 steps just incase.


the paint is Gloss black and looks great but its dusty in the pic
