Its not car paint, but Montana spray paint is definitely the best paint in a spray can. I dont think you will find actual car paint in an aerosol can, but I could be wrong.
use rubbing compound from your local auto store. theres different strengths so be carfull. this stuff is also good for cleaning up the paint by taking out sratches and removing wax. use elbow grease...
different people have different favorites that they always use. You just have to take risks, judge and test for yourself!!!!
Montana spray cans are by far the best type of spray paint you can...
