Sand is great...when it's not on you. Lol, you have to be way more careful too when it's someone elses car and not yours. I use the showers provided, and I take my merry sweet time getting it all off too! I have to use a CRAPLOAD of water to get it all off, so the jug of water thing wouldnt work for me. The only thing about the shower is the water sprays out retardedly and it hurts when it's on bare skin, lol. What about those little towelette things? Would they work for your sandy problems? Or a spray bottle(s) of water?
