I have a 1964 C10 Short bed Step Side. It appears to have been painted twice plus the original paint. I have decided to take it down to the bare metal. I am considering media blasting with Garnet. I have a cheap supply of garnet is why I am leaning that way. My question is… Is this the correct way to go or can i just sand it down and paint over all the other paint. Im not sure what type of paint the other is. I am going back with the Eastwood single stage urethane paint. Thanks for the help.
