I recently acquired a full set of plastic cargo panels for my 1984 Camaro. The panels are in relatively good shape but have a few minor scratches here and there. Have any of you attempted to refinish your panels to repair the scuffs/scratches? If so, were you able to replicate the grain/pattern of the plastic over the repaired area?

I'm restoring my car and want to do a really nice job...so I'm just looking for advice from people with past experience. Thanks in advance for all replies!
