Thanks again for the help... and another noob question. A friend has graciously offered up his garage (mine is too small) and I want to make sure I don't leave it a mess. How much paint comes off during wet sanding? Do I have to be careful of staining his driveway? Killing the grass? Anything else I should be aware of?

Thanks again. I'll be following the prep instructions for the peeling caravan by marq back on pg. 58, knocking off the paint in my driveway so I don't leave at least that mess at my friend's. Thanks Marq!
