But if the body kit on the car is genuine and fitted at the time of delivery of the car, I can't understand why you are having so much troubles? It seems to me that you got a dodgy painter to do the car. It's not the body paint is it, it's the actual body kit. Bumpers, spoiler, bonnet spoiler and skirts? If that is the case, it's the local painters that stuffed up as the cars that come into the country from Japan don't have body kits fitted to it but are stock, all the body kits are put on at the dealership...
Hope that clears up the problem. With my Celica ZR we have not had any factory paint... So it's the dodgy local paint job...
