Anyone ever use POR-15 on Rocksliders?
Hey all, looking for some advice, I have some rock sliders that just have black rattle can on them right now, and they are starting to show some surface rust. i could sand them down and rattle can again, but was thinking that maybe the POR15 undercoat would be a better option? Any opinions?

I think a roll-on bedliner would be a littler more durable. I've used this before to protect parts & holds up well as long as you prep correctly: https://smile.amazon.com/gp/product/...?ie=UTF8&psc=1

por15 is not UV stable , it will break down .
that being said , I had some leftover , so I decided to "test" that . I put it directly on my rear bumper , didnt even wash or prep. ! It started to chalk after a few months , and a good 4 years before it started to lift .
I have done it one more time since , again no prep. , and still seems to be holding up .

Thanks slacker, if i can get 4 years, that's great! Appearance is less concerning to me than anti-rust, hah.
Maybe if I'm feeling really snazzy I'll top coat it with a rust-oleum or something to try and add some protection (Colorado Sun)

So the POR stands for Paint Over Rust. That is really all it is good for. It converts rust into a paintable surface. (And like stated above it needs to be painted over to keep from turning chalky) If it's not rusty, it will just flake off. Had a buddy paint a ladder rack on his truck with it and it peeled off in less than a year because there wasn't any rust for it to attach to. Plus it's $$$. Rustoleum is your friend here, especially since the point of rock sliders is to drag them along rocks. No sense in dragging $$$ paint off.

For those where money is no object, this is probably the best protection for parts, including the body. They have franchises all over the US: https://linex.com/

Reviving an older thread with an updated question.
I am welding a replacement floor panel into my truck. Large area panel (basically the entire drivers side floor). I don't care hot it comes out looking too much, as long as it is structurally safe and rust proof.
I was going to peel back the OEM undercoating (pretty old at this point) on the donor panel, and on the remainign portion of my truck, perform the weld, and then POR-15 over the weld on both sides. I asked POR-15 for their opinion on blending their product and the OEM undercoat and they basically said "don't, it can't seal up." They want me to remove as much of the undercoat as possible and POR-15 the whole thing. I'm not sure that would leave me any realistic seam to work on without doing the entire truck (not enough time for that option at this point)
I am planning on going to more of a fluid film/ cosmoline prep on an annual basis to help future rust issues (Like, soon). Is my best bet to not worry about any sort of tougher undercoating, just paint the welded area and then FF every year? I want to do this right, and not have to do it again, but there sure seem like a lot of options out there. Am I going to screw it up and cause myself problems if I POR-15 as much as I can get to (top and bottom), blend into the original nasty undercoating where I can, and then spray with an inhibitor every year?
I'm also thinking I will lay down killmat over the entire top side once I get it painted with something. Any issues with Killmat over POR-15?
