67-69 barracuda rocker trim

i have dont have wheel well trim, never will.. I like the look of the gilled rocker moulding. I don't have rust rust. I have a few bubbles comming out on the rockers after being painted for over 4 years. figured i could grind them down, paint over them to seal it and then put the moulding to cover my fix.

I do understand about them collecting crap behind them. It pretty much like how a vinyl top rusted roofs
