Sorry, I thought I put purchasing info in that post.
I could only find black POR-15 primer and one or two colors of HardNose paint in the local auto body/paint supplier. I'm not in a huge town-30,000 people. Best option is to buy it all from POR15.com.
Salmonjammer first posted up in another thread about POR-15. He put gray POR15 on his frame and ammo cans early last season and said it's held up great. He does store his boat inside.
I put black POR15 on my frame last season, my boat lives outside for about a month in late summer, and by the end of that month, the black that had been glossy was all chalky and left dark marks. POR warns that it doesn't have good UV resistance. They're not lying.
I was otherwise happy with the product--good gloss, and super hard finish. No rubbing on the frame, and no buffing of the paint when I pulled straps across it. Their HardNose paint is equally good, and has better UV resistance.
New galvanized doesn't have much for paint to stick to. I used some pool (muriatic) acid to etch the galvanized and wash off all the oil/grease that seems to accompany new galvanized. POR also offers a prep wash that I didn't try.
POR-15 has some kind of magic stick-um. If you get the galvanized reasonably etched or sanded, POR WILL
stick to it. Both POR-15 and HardNose are moisture-cured urethanes. POR-15 cures only with exposure to air, so keep your can sealed! HardNose comes with a catalyst that you mix 1 part with 4 parts HardNose, but it's still moisture-cured. Wear gloves and old clothes...it isn't washing out!!
So...it dries to the touch in about an hour, but full curing is 3-4 days at average ambient humidity. They recommend you put the HardNose over the POR from 1 hour to 1 day later. Since you have to order online, buy everything you need in one order. If you run out, you'll be too late, and you'll have to scuff-sand the entire thing to get the next coat to stick. Ask me how I know. :laughing:
I figure that 1 pint covered 110lf. With that light yellow, I needed 2 coats. There's just one coat of the Glisten PC (clearcoat--basically the same stuff as the pigmented HardNose). I mixed in gold pearl flakes from Custom Paints | Candy Paint - Metal Flake - Temperature Change Paint - Chameleon Paint - Pearl Paint - Clear Coat
I do think the set screws would chip it, just where they touch. It's a pretty awesome system, but I don't think either it or powdercoating would hold up to set screws.
