My employer hired a contractor to paint our silos on site. This contractor spray painted on a windy day and all the vehicles in the parking lot have overspray. This contractor says he is going to bring in a "professional" group to clean up our vehicles of the overspray. My question is, if someone, other than my dealer's vendor, messes up my car by trying to correct the problem, will it void my vehicle warranty? I have a 2016 Chevy Equinox, Patriot Blue, that I have just made my 4th payment.
