Por-15

I'm starting to get some rust on the undercarriage of my Wk and thinking about painting it. I've been hearing about this POR-15 product and heard great reviews. Anybody here have any experience with it on their Wk/Xk?

I coated most of the undercarriage on my 2008 WK with POR-15. I cleaned it really well. Used the metal prep on actual rust areas with a wire wheel and brush. Be careful because the metal prep will ruin paint. Applied several coats of the Por-15 and when the last coat was tacky I covered all it with nice 3M rubberized underbody coating. That has lasted for the last couple years with keeping it rust free. I plan on touching it up and reapplying every three years or so. In Iowa they go crazy with the salt applications so its nice knowing my Jeep won't totally rust out on me. Plus the Jeep is a daily driver and doesn't get washed as much as it should in the winter.

So after I apply the POR-15, do I paint over it with something like Rustoleum?, not a fan of rubber coating.

POR-15 works fine by itself. I've used it on other cars. Great stuff!

Mine has rust inside the fender on both sides, behind the foam insert and the wheel well. This summer I want to clean and use POR-15 inside. I also used it on my Cherokee Country about 6 years ago on the floorpans..It worked great.

I did my suspension and rear differential with por15. Holding up quite well after a winter of sand and salt. I didn't top coat it with anything. The thing about por15 is that it doesn't have any UV protection so any parts in direct sunlight will change from gloss black to flat black. That is why you have to top coat parts exposed to sun.

I just wasn't sure if painting over dif bolts would give me a hard time removing them. This stuff seems pretty tough!

I know this thread is a year old. But wondered how everyone product is holding up this past year so far.
My plan is to wire brush mine, the use the POR15 cleaner and metal prep, the to use Chassis Saver on top of it. The chassis saver is suppose to stop rust, seal it, and leave a flexible coating that isn't supposed to crack chip or peel. I also figured after that I would try and 3M Bedline or similar spray areas that look like would get beaten and rubbed more often than any other place.
