I just want to second Squeeze on the electrolysis. I was intimidated a bit by the idea but once I decided to give it a small scale test in just a small wash basin I was sold. I live on a lake so am quite conscious on contaminates getting away from my work area. I look funny vacuuming the drive way after stripping and sanding but feel its the best I can do all things considered. If you want to give the electrolysis a try I'll post a link to the site that I found giving very good directions and info. I think the guy is an anthropoligist or something like that so he explains it for non mechanical folks.

Give me ambiguity
or give me something else
