The Stovebolt Site Forums The Shop Area Paint and Body Shop stubborn rust

Well, we've finally jumped into our project with both feet. One fender will serve as our test subject and we're busy stripping it down. Several on the forum suggested the nylox stripping disc and it certainly works as advertised. Not quite 'hot knife thru butter' but awfully close. Turning our attention to the underside of the fender we find gobs of rust. Most did in fact come off with a combination of the nylox disc and wire brush but there is a stubborn/deeper patch that runs the length of the fender where you can imagine water/gravel impacting. What to do boys? Just primer over this, use a rust stabilizer ?? Thanks again all for the help.

I would blast it with a fine media, use rust converter on what's left (if any) and charge on as normal. You can get small sand blasters (think they're called spot blasters????) from Harbor Freight that will do the small area you need done.

We are ready for the rust stabilizer and a cursory 'net review shows many available. Any better than the others? The price differential seems rather wild going from fairly inexpensive to grossly so. Is this another case of you get what you pay for? Thanks again all for the advice.

I can't remember the name of it but there is a rust remover and concrete etcher available at Home Depot in a squarish gallon jug. The product has a dark green tint to it. Only time will tell for sure but it seems to work well, turns the rust to a dark grey tint when it's done. then just wire brush, prime and paint.

OSPHO is the brand I have been using for the past couple of years and have found it to work very well. You can find it almost anywhere
