Im restoring my wheels that I bought the curb rash isn't deep it looks more like someone scraped it around the edges but it's still curbed. Many people said to use bondo as a filler but a buddy of mine said to use self etching primer because it's also a filler and you just sand it down. Its the rustoleum brand; anyone have any experience with it? Depending on what I hear I'll go about using it.
