I have a 91 Toyota SR5 that has been driven in New England most of its life. I've had to replace all the brake lines and fuel lines already, but now I need some advice on how to restore my frame. Seems like it's mostly surface rust, but some of it looks pretty bad (adjustment for front end alignment won't move, spare tire mount is junk...etc.). Any suggestions?  

This is extreme but I have been using it for years. Spray frame down with oil used gear oil using a paint spray gun and compressor. It will stop rust dead and loosen some it it too. There are additives in it that attacks rust. It will smell for a bit and park it for a few days where it will not drip on driveway but it does work.  

Thanks... I'll give that a try.  

there is also a thing you can try from summit racin it turns the rust back into metal i'm goin to use it on my S10 so if you do try it tell me how it works if not ill tell you uf i try it 1st all the feedbeck i heard from it was good
