My Custom 4x4 winch bumper was powdercoated, and it's toast. Not to knock his products, but my coating only lasted about 3 years in the IN winter. I've sanded and re-coated it with Duplicolor and Rustoleum to no avail. This year I'm gonna try the roll on stuff. Honestly, if I were you, I'd powdercoat it THEN coat it with spray on bedliner. Rust has made me bitter :gonnablow
