I have just noticed a few problems that my be due to bad install or design flaw. After getting a spoiler installed I noticed that the bolts for the spioler (pic.C) are hiting the metal around the trunk and denting it and cause the metal to be exposed (Pic.A and B) and therefore lead to premature rusting. Anyone else have this. the other issue has more to do with stone chips in strange areas. I'm getting stone chips on the edge of the trunk lid, right where it meets the tailights (Pic.D) . Anyone heard issues concernig this? TIA.
