my wheels are fine, they have been bedlined for 2 years and look the same as the first day I sprayed them. Same with my bumper end caps and cowl, but mine front bumper and rear bumper (use to be chrome) I have chips from rocks.A few thick coats of bedliner itself has proven sufficient for me. I've prepped and coated 5-spoke SE's with a few coats of bedliner and they held up perfect for about a year.
