Hope u guys r joking around about the f/g rusting......cause that is not possible.  but ya like everyone else said it is fixable.  Just take it off the deck lid first then clean it, grind it, f/g it, (u could just use fiberglass bodyfiller like Duraglass) then apply bodyfiller/glaze, prime, and paint

Bondo wont help that.  Not worth it in my opinion.  Youd have to grind it down to where it starts and then reglass it or something.
