I got some rust on my underbody. I was thinking of using black rustoleum (sp?) to cover it up, and help prevent it from growing. As anyone done this? Any suggestions?

 

I use Wurth Rust guard. It is a water hardening paint/coating that bonds to the metal and rust. It works wonderfully. If you do use this product put a layer of saran wrap or plastic between the can and the lid because if there is any paint in the lip etc you will never get the lid off again. I just purchased a 99 Ranger and used this on the underbody.

 

Not to jack, but can you get this at a Walmart? Living up here in Michigan, my undercarriage is in rough shape.

 

I just did this to the whole underbody of my truck a few days ago, i cleaned all the rust, wax and dirt off the frame then went to town with a quart of gloss black rustoleum and a foam brush. It turned out great.
I did the rear end of my truck with the same paint and technique about 6 months ago and it still looks good.
I will try to get some pictures up for you today or tomorrow.

 

Wurth Rust Guard is not available at the Evil Empire. You will probably have to order on line.

 

If you're gonna do it, then do it right. POR-15.

 

No, that's do it "l2en style". Aka "if it costs a lot of money then presumably it is the best option".

There are other products that are rated to be as good as por-15.

 

30 coats of spray paint

 

Any rust killing type of paint should work just fine. Just make sure you clean the framerails and such good before you put any paint on them.
