Broke out the grinding wheel and stripped paint and rust off a number of spots on my steel winch bumper this weekend. I cleaned and painted with POR15. Their rust preventative is glossier than my flat black powder coat was. Questions for the group:
- How stable is POR15 to UV? Wondering if I should just paint the whole thing and leave it gloss black instead of flat black.
- POR15 has a semi-gloss black top coat available. Anyone ever used that and if so how glossy/flat is it really? Will putting their top coat on make it hard to touch up in the future?
- Anyone have experience with using Rustoleum matte clearcoat? I'm considering just painting the whole thing in POR15 and then clearcoating it.
FWIW I'd been using Rustoleum flat black to do touch-ups for the last few years. The color matches initially but UV will fade it over time to be a dull black. Also it apparently does **** all to actually protect the steel since the spots I've touched up (without a clearcoat) are the ones that have rusted the worst.
Ultimately I may remove the bumper, strip it, and paint it, but I'm trying to avoid that because it's 200# with the winch, winter is coming which will suck for painting in my garage, and frankly I know it's just going to get scratched and need maintenance in the future anyway.
