Rust Removal

[ryaneiferd]

Other than media blasting, does anyone have a recommendation for removing rust from tight areas? I am currently using a 4" abrasive disc on an angle grinder and a 3" wire wheel on a drill, both of which will be difficult to use in some spots along my chassis.

Fresh ideas are appreciated. Or a link to an old thread would also help.

The is a product called The Works toilet bowl cleaner sold at the Dollar General stores and it has 20% Hydrogen Chloride in it. It will remove rust pretty fast and if you wire brush the loose rust off and the brush or spray it on in a matter of an hour it should do the job. You may have to brush it on every 10 minutes or so to keep it wet but it works. Flush the areas with clean water and maybe a baking soda solution to prepare it for painting. Rust-O-Leum has a primer that is called Rust Reformer Primer and it bonds with rust to prevent further rusting. You have to put a coat of paint on it to finish the job.

Most primers will absorb water so it's not a good idea to leave primed areas unpainted.

Recently I've experimented with Electrolysis which I think is the best way to remove rust from hard to reach areas, as well as phosphate based rust removers which are available at any hardware store but you still have prep work after applying chemicals.

And if you need a break from rust removal, take aluminum foil and roll it into 8-10 balls small enough to fit into a 2 liter soda bottle.  Pour enough "The Works" toilet bowel cleaner in to cover the balls.....put the cap on and stand back.  

Makes for a fun Saturday night

I have used a POR product for rust removal and it worked pretty good in tight areas. You just spray mist it on. I am going to try some Mastercoat metal prep / rust removal next week. You just have to be sure to rinse the stuff off before painting. I have also used some phophoric acid with some degree of success, but the POR did a bettter job in the tight spots. We'l see how the Mastercoat stuff works.

Leave "The Works" on chrome long enough and poof...no more chrome. ( I made this mistake cleaning a sink drain cup) �Burns the &^($! out of your hands too.

George, �I used the Mastercoat Silver primer on most of my Jeep. �Pretty darn good stuff. �Are you going to use it after the rust remover?

I'll try The Works out, seems to be popular. And I will probably skip the HCL bomb for now and just watch other people on blow stuff up on youtube.

Hey Tim,

Been traveling lately so I have not been on the forum much. I got my package from Mastercoat this last week. Saturday was such a nice day I decided to do the metal etch from Mastercoat. I was pleased with the look and my plan is to do the silver primer as soon as the weather warms up again. When I sprayed the metal etch on it appeared oily but I used a rag to wipe it down after spraying and once it dried it looked pretty good.

Did you spray the silver or just brush it on? I think this paint is bad to inhale (I use a reserator all the time) but I may get a fresh air mask. Looks like if you don't spary the primer it would be hard to get into the tight areas of the frame that are partially boxed in.

I'll get some pictures loaded in tomorrow of the before and after metal etch look.

Hey George,

I didn't use Mastercoat rust remover.  By the time I settled on the Mastercoat Silver Primer, I had gotten rid of my rust.  I brushed some small parts with the Silver.  Stuff like the tranny case, hand brake drum, engine block and some of the harder to reach areas of the frame.  I sprayed the frame, axles leaf springs and tub.  

The warnings about not inhaling this stuff really stuck with me, so I did wear a respirator and had the garage doors wide open.  Otherwise, I really liked the primer.  I had a gasoline tank leak.  The gas sat on my recently painted floor pans.  The gas completely stripped the Gilispies paint and primer, but did nothing to the Mastercoat Silver.  Also, during re-assembly, I banged stuff around a bit and chipped small areas of my top coats.  The Silver doesn't chip off.  

As you have probably read, it cures with moisture. It took forever to dry here in Colorado.  (virtually no humidity)

Ryan, we have taken your post in a few directions.  Sorry.
