I've searched a bit and found few things. Sand blasting works very well but I have 1 car garage. Also I found a post where you put the part in water, add salt or baking soda, stick a rebar in the water and then hook up battery to rebar and rusted part. Well, these two won't help me since I'm trying to remove rust off inner fenders and floor. It's not on a Z but this is the only forum I'm registed on where people have experience restoring cars. Anyways, I used a wire brush and electric grinder but it doesn't work so well. Can't get rust off uneven surfaces and corners. Some one recommended me this. How well does it work and how fast does it wear out? Anything else that's really good and fast?
