I got a set of short track shrouds for a whole $20, they looked rough in the pictures. I opened them up today to find something like sprayed fiber glass on them, cracks and scratches. I want to fix there cracks, put a smooth serface on them and paint them black, anybody know what to use for that??? I was thinking of putting on that dino-liner stuff for truck beds, that should do the job in one step. Will this eat up the plastic??? These shrouds are too bad to try to get back to a shiney red. I guess for $20 including shipping, you get what you paid for, now to use them for something.
