Guys, body is coming off frame soon- question, I have a rolling rotisserie that I've borrowed. Car was originally under coated when new. Since I have this rotisserie, would you transport and just have the whole body blasted vs sanding the paint with regular tools? I figured I would spot sand blast undercarriage where need be. I'm going to lizard skin bottom of car anyway. What would you do? What does a full media blast cost roughly? Thanks!
