Car lots are difficult walk the lot make a list of what you see then walk in and introduce yourself to the Used Car Manager. If you sow some out there his guy may not be coming around often enough or possibly he does'nt have one. Give him your price tell him what you saw. You may have to keep stoppi...
If you want your repair to be even less visible and harder to find; use pit polish.
A thirty second shine with pit polish and a paper towel works great.
A five second shine with pit polish and a polishing wheel will achieve the same results.
