It should be mentioned that baked on acrylic enamel over 2 or 3 coats of primer is not as easy to get off with electrolysis as the interior paint on the dash frame and steering column. It's still a good way, just not as fast.

Since I want to use electrolysis on hood, fenders, trunk, and doors, I need a bigger pool. The 52" round hard plastic one was a good starter for about $17. Wal-Mart has bigger soft plastic inflatable rectangular ones for about $50 + an inflator for under $20.
