I have a friend that has agreed to let me paint his car, yes you heard me right!! I have over the last few years created a library of advice and information on everything except one topic. How do you calculate how much paint is needed for a particular job??? I am planning on shooting bc/cc and it will probablly be MS or PPG paint. The car I will be painting is a 1990 Mustang Hatchback. I would apprciate any advice on how to calculate needed materials or if someone could just give me an estimate. Thanks for your help.....
