By the way -- unless you're building a high zoot car -- to show etc --- you don't really need powder coating for a good finish on the frame and running gear --- ever tried POR-15?? You can brush -- or roll and back brush (called tipping off) with a brush.... and if you're stuff is really clean - and your area is fairly dust free... you can get a fabulous finish with the stuff.
We did my buddies 55 Post - had it on the rotisserie -- cleaned it with a propane torch ( a soft flame heats the "tar" and gunk up just a bit) making it MUCH MUCH easier to scrape with scrapers - metal and plastic versions -- then cleaned it MULTIPLE TIMES - with mineral spirits - then with a paint pre-prep until our white rags didn't show any residue... then rolled (small 3" rollers on a cage with real fine oil paint rollers) and back brushed it... came out flawless like it was sprayed.
I have spray equipment - the one guy rolling the other tipping off was faster - less messy and easy peasy.
Tell you one thing if you've never used it before - this crap - when it gets on something - ain't NEVER coming off... that includes the cement floor... your skin - or your frame or underbelly!! Seriously... it's the hardest damn stuff I've even seen! It's just got to be clean! Drying time is "longish" so the dust free - or pretty lint and dust free area is important. We left the body rolled onto it's "side" so the lint in the air wouldn't settle on it. Worked out great.
