Purchased my new (used) Grizzly 350, 2009 version. It had some scuffs on the fender so having done paint work on cars almost all my life, I wet sanded with some 3000 grit paper and when I went to buff it out, it had absolutely no effect. There's no clear coat on these things or something? Is it possible to restore the shine back on the sanded surface somehow? Someone enlighten me on the type of paint they use on these things.
