Paint job Options

[partwerks]

My car is on it's second color already, and I would like to change it from the previous owner.

I'm wondering how the body shop goes about painting over existing colors to get it to stick??

Personaly I would never paint over an old existing paintjob but if you choose to and many people do, a mechanical bond (sanding) is good enough though some might suggest a adhesion promoter also then your primer sealer etc. I strip all exterior paint with paint remover (aircraft paint stipper) and all interior, underside etc. with media blasting. If the exsiting paint has checking (small cracking that looks like dry desert mud) this will show through the new paint no matter what. If not right away, in a very short time it will. This is just one of many problems that can swell through and show in the new paint job and not to mention the old filler that may be in the car that is ready to give up. Hope this helps. It's a dirty time consuming job to strip to metal but it's well worth it in the end and you can skip the blasting of the interior underside etc.
