i went to an auto paint supply store today to get phosphoric acid to neutralize/remove some surface rust on the back of my fenders. they didn't carry the acid, but they had a product called rust converter, made by klean-strip. it says it "turns rust to black primer." it also says it "dries to a hard, sandable, paintable primer." it costs about $6 for a 10.25oz aerosol can. has anyone used this? how well does it work? thanks.

i'm from the old school of body work,i just can't accept you paint something on and hocus pocus the rust is gone,all thats left is sandable primer.i know alot of guys use it but when i'm doing a resto i use a lot of navel jelly on parts that are not rusted through,just keep putting it on and wire brushing it till it's nothing but shiney clean metal.then prime with epoxy primer. if you sandblast you are decreasing the thickness of the metal a little and if your in a rusty area you'll have nothing but pinholes. i get my navel jelly at oriellys or you can get a ppg metal prep that sprays on,a little harder to keep wet.por 15 also has a metal prep? larry

I don't think that stuff is what you want. Those finishes (and it is a finish, not a rust remover) supposedly "seal" rust and keep it from spreading. Naval Jelly is a fair alternative and I have even seen a liquid (like OxySolv) version of it.

I used muratic acid on the front end I purchased for the 62. It had set under a tree and paint had worn off and it had plenty of surface rust. The muratic acid did the trick and brought it back to bright shiny metal. You can get it at any pool supply or drugstore...

I used that stuff on the floorpan in my dodge, it will only work if you get it really clean. It sprays on clear, and dries black so you will know if it worked or not. Problem is you have to get it so clean, you may as well just sand the rust off to begin with. I won't be wasting my money on that stuff anymore. I did my whole floor, and only had a few pebble sized spots of black appear, otherwise it didn't change anything. Skip the cheap fix and do it right the first time like the others recommended.
