body blasting!!!

I would suggest doing some research before you undertake this. You are going to be shooting different media to strip painted areas vs rusted areas. Also, you must be careful with your pressure, distance from the surface and what angle you are going to be blasting with. You don't want to heat up the metal and warp it. Also, consider what you are going to be sealing the exposed areas with once you are finished. What air supply are you going to be using? Those pot blasters use a lot of air. Just a few things to consider. Good luck.
