Oh, and when doing tear down and run into stuck bolts, I use a MAPP torch to heat the bolts, burn up rust, etc. When I do it in an area where there is paint that I don't want to damage, I get a squirt bottle and keep the paint wet while I'm heating.. the laws of thermodynamics won't let the paint bubble because the heat will transfer through to the water. I never read that anywhere, so I count it as a self-taught trick. ;P
