Has anyone had experience with undercoating their rigs? I have seen some stuff through the Wrangler Catalogues. It seems it could get expensive because it seems that it is painted on and to buy a gallon of the protective goop is like $35.

Anywho, if anyone can let me know of the Pro's / Con's that would be great.

Not really sure it would be any added benefit to those that wheel (rock in particular). I would think just about anything you put under there would get scraped off rather quickly.

Dunno, might ward off a little of the rust up north, but wouldn't be much help at all down here in TX...

you dont need to spend that much moeny
its all about the prep work
LOTs and LOTS of time
sand everything down to shiny metal then spray EVERYTHING with some rustoleum, like about 3 coats of rust protectant, it will do fine, but the key is to get it EVERYWHERE, and also to have EVERYWHERE prepped to a nice shiny metal with NO rust underneath the paint
it will work great be cheap and stay on for a while

imho, its just about worthless unle4ss you pull the tub..... i plan on pulling my tub off next summer and taking it and frame down to bare metal to comepletely under coat them both, i want my rig to be complelety rust proof. if you do it with the tub and everything else still bolted on, you'll most likely only get the places you can reach which can lead to alot of rust in unseen places, leaving it to rot away at you're frame without you ever knowing

POR-15 is a good product for this. Although it isn't the same as removing the tub and stripping down to bare metal it gives you the opportunity to protect the chassis and under body without disassembly. The other benefit is that you don't need to rub down to only metal. Since oxidization (rust) occurs from the introduction of oxygen (including H2O) to metal the painted parts are better guarded from rusting. The chemicals in POR-15 protect metal like all get-up and prevent it from coming back out. Just scratch and sand down some and be wary around bolts.
