Re: How to correct these defects?
Werent you the guy that had damage to the front from a NYC snow plow? I would suggest moving if you want to keep that thing nice.
As far as the defect, it looks like water or chemical stain. Try polishing it out. Start with something like Ultimate Compound. Did you ever get a polisher?
Griots Garage 6in ROP, 3in ROP, pneumatic 3in polisher
Flex 3401, Porter Cable PC7424 (the old non-XP model).
