Good lord, gawd almighty.... got your hands on the ultimate rare w112 doncha?

Have you thought about hiring a couple of forklifts to raise or patially and gently flip the car with old mattresses and/or sofas for padding to keep the work in your shop? Thats what i'd do and then rely on the opinion of ctsoda.com for what works best (sand, soda or glass bead) without letting the car out of your sight. Heck how much room do they need to shoot the car? Might not have to be entirely flipped on its side at all.
