Need some help here guys. Took my car to be painted and the body work so far looks good, but here is my question. The body was sanded in a few places to bare metal like where the vinal top was and a section of the trunk. The problem is that he is letting it sit without primer and it is rusting. Also there are a couple small areas with body filler and surface rust around them. I talked to the guys about it, and he said they would sand it a little more and use vinigar to treat the rust. I thas been at least 2 1/2 weeks with the surface rust forming and the car sometimes sits outside. Is this normal practice? Do body shops do this? He is very busy with insurance work, so I'm not trying to rush the job. What do you guys think?
