How can I control this rust?

I live up in minnesota, the salt is rough on the underbody of vehicles needless to say. My jeep seems to have a bit (understatement) of rust under it and looks horrible from 20 feet away. How can I turn the underbody back to black? Anything I can put on it to resolve this problem? Do I have a few options?

Thanks so much guys.

well the options that immediately come to my mind would be...krylon fushion, i swear that stuff is a miracle in a can! or if you want somethin a bit more durable they make spray on bedliner in rattle can, i used that on my old chevy truck and was pretty happy with how it looked, or the last option buy some aeresol undercoating, i dont like using that stuff though cause it makes a mess.

I just restored a trailer that was sitting by the ocean for a very long time.

easy answer POR 15 the stuff is awsome. one quart and i coated a trailer setup for a 18ft boat 3 times. the stuff goes forever its awsome. it will seal the rust and you will never have to deal with it again. I would use that on all the metal and get a good undercoat in a can for the tub.

Krylon Fusion is for plastic and it doesnt seal up rust.

Por 15 it and it will be done right the first time.

Just make sure to top coat the POR15 after you use it, it has no UV protection.
POR15 and then paint it. Go over it with a steel brush and rags with a degreaser then put the POR on. You also might want to consider undoing your body bolts and temp lifting the body off the frame a few inches to get at the top.

In addition to POR-15, I've heard good things about Eastwood Products Rust Encapsulator.

Haven't used either (yet).

Additional note, the prep is most important! If you just slap it on a dirty crusty frame, it won't adhere, and will fall off in no time flat, so prep, prep, prep!

After treating the rust you may consider some Duplicolor truck bed-liner in a rattle can. I just used the stuff to do inside my fender flares. I also sprayed all the exposed frame rails for asthetics. Have to say I'm very pleased with how it turned out. And the stuff has a really tough, sealed, semi-gloss finish that sheds alot of dirt and grime. May be something to consider.

Tony, if you are serious about fixing it "right" go get yourself a steel brush attachment for an electric drill. Clean off the frame, control arm mounts, axle tubes etc., anything metal that you can get to and clean it up real good. Get a strong degreaser, clean it up, and POR-15 it. PAINT-OVER-RUST #15. The stuff is AMAZING, just DONT get it on your skin..it will take forever to get off..... That will keep the rust away, and look REAL good. POR15 also makes different paint colors, a silver, etc. if you didnt want just black.

If you just want to make it look good, and not worry about the rust, go pick up a couple cans of Rustoleum, semi black (or just get the grill paint one), get some sand paper, clean it all up with the sand paper, wipe it with a degreaser, and spray it with the paint. Its not going to be pretty for 10 years that way though, and it WILL keep rusting under the paint unless you A. replace parts or B. POR15 it.

i know fushion is for plastic but it says on the can metal also, i sprayed it on my frame rails at work when i took off my steps as a quick fix until i had the time to primer rock guard it and paint it, and here a month later still looks good, AND ive even had the jeep buried in the mud a couple times, thats stuff the best invention since sliced bread!
