Another rattle can paint question: does can primer need to be sanded off before good primer is put on?
I painted the body and fenders with rattle can primer to avoid surface rust. I'll drive the car for several months to work out the kinks and have a professional paint it in the spring.
Will the professional have to strip the primer or can he just sand it and put better primer over the rattle can?
Thank you in advance. Bob
Robert, in my experience, primer will not prevent rust. It will delay it, but it is porous and will allow rust to get a hold again. I would not drive the car and then expect a later paint job to hold up. If you must drive it, give it a topcoat of any compatible finish, to seal the surface.
Hope this helps.

To answer your question -- yes, your painter needs to strip off the rattle can primer you have applied prior to applying a good commercial grade primer and topcoat.
If your painter knows what he is doing, and he is aware that you have primed your car with an aerosol can, he will make this recommendation himself.
Not what I wanted to hear. LOL But Thanks!
