If you haven't started stripping it Dave get it tested first mate. No chance of damaging fresh paint doing any mechanical work. Shirl's brother always used to do this and I never did understand his logic. Either way, good look mate.I've had bumpers done in the past and been happy but having 3/4 panels done at a time will be different. I don't think I'd be happy with the other panels if I just had done what was needed. They would not be as fresh and possibly not be a perfect colour match like you mention. I always said when I bought the car one day I may get it resprayed, my brother had his old E36 done and after seeing that I've wanted mine done even more. I've got through buying 2nd hand panels and touching up here and there in the past so now is the time to treat it. I just hope it's everything I'm expecting and that it doesn't fail the MOT as it's due next month after spending all this money
