Your better off getting a portable tent and go to your local sheet metal workers shop where they do structural steel work and purchase floor grating put very thick Poly sheet the kind used in concrete forms when making a vapor barrier down first put the grates on bikes to elevate the grating about 2 to 3 inch's from the ground, drive the car or put the part on the grate blast it and recycle your sand or media this will also keep the dust down in your tent. The nice thing is you can use either a pressure type blaster or just a gravity type unit

What John E posted on the shop blaster is very accurate. At best they kind of worked for small spots on the car’s skin but doing inner rocker panels with many inside corners would be a real stretch, you’d be there a long time and a lot of abrasive would escape the brush head. I was given mine by a disgusted body shop owner and it now sits in my mom’s basement, very rarely ever used and totally unloved…… what more can I say except I see them for sale at almost every swap meet I go to. ~ John Buchtenkirch
