To bodywork and put a car in a catalyzed primer, I would plan on $300-$500 for materials.

When I'm doing a one color BC/CC job, I usually spend a total of about $1200 for materials.

You can do these for less, but you will end up redoing the job soon, so what are you saving? If you do a good job, and take care of it, it will last 10-20 years or more!
