rust questions

[Russianwolf]

this is in relation to the truck I just bought. It has some pretty significant rust and I'm looking for advice on tackling this problem. Doing some research I happened on two products that mean I wouldn't have to sand down to metal.

POR-15

and

Rust Bullet

both of which you remove any flaky rust and coat the remaining surface rust with the product. This kills and seals the rust and no more problem.

Have any of you ever used these products, or anything else? What would be the best way to go about this.

Once I get the rust in check, I will be doing the body filler where needed and then getting it painted.

POR-15..

Mike,
I am no expert, but I remember this product from the days when I was frequenting the Jeep forum. I recall having to scuf the surface before applying POR-15. I am sure you've seen their web site and FAQ's.
You may also want to check out Eastwood - they have a product called Rust Encapsulator that comes in red, black, silver, and clear.

I've used quite a bit of POR-15 and think it is great. The rustier the metal, the better it adheres. The only thing it has trouble adhering to is new metal. In that case, you have to etch it first to give the POR something to cling to. Once it dries, it stops all further rust and I think you would need a cold chisel to get it back off. The big thing to watch out for is getting it on your skin while working with it. If you do, you will be wearing it for a couple of weeks. Also, be sure to put some plastic wrap over the can before putting the lid back on, if you ever want to get into the can again. Finally, I would advise buying smaller containers rather than one big one if the project is going to stretch out for any length of time. The shelf life once the container is opened is nothing to brag about, although it can be extended by keeping the resealed container in the refrigerator.

Yeah, I went back to the websites and saw how much prep was needed for the POR-15 and was a bit discouraged. The Rust Bullet seems simialr to the Rust Encapsilator, but I like the metalic silver of the Bullet better.

Looks like I need a good wire brush, a couple quarts of this stuff and a small roller and brushes. I'll have this jeep looking good again yet.

Frumper, quick question since you use these a bit. where you have ovelapping metal bolted together, how do you treat this? just go over the joint and hope that you get it all, or disassemble, coat, and reassemble?

I haven't used it yet, but I bought some Rust Bullet after doing a lot of looking and reading. The independent test results were amazing.

Hey Pappy, I got some good news. Rust Bullet can be sprayed with a Wagner power sprayer if you already have one. Or an HVLP setup. Here's the Email I got from them.

Hello Michael,

Yes you can use your sprayer. Make sure you clean it before you use it and right after using it. With some Xylene, Rust Bullet is a moisture cured product any moisture in your line and it will start to cure. A paint store will have some or a home depot. Use Acetone if Xylene is not available.

I've only used the Lock-tite product (no kidding) and was well satisfied on mower decks and such.
