Anyone use POR 15?

[Autism Family Travels]

I am thinking my Jeep will be in the family long term. I am thinking about painting all the chassis, supension arms, axles, steering components in POR 15 to stop the rusties. Anyone use this stuff? I have been doing some reading and think it would be awesome for the bottom half of the jeep since it will keep it nice and black and rust free.

I sell POR15 alot of restorers use and people use it on hotrod builds

Cool, so it should do what I am looking to do with it? I plan on dissaembling the jeep running gear painting the entire bottom end of the jeep, with all the parts and then re assembling it.

Yeah I recommend it along with steel-it

POR is a great product but a pretty complex, labour intensive process. There are other simpler single step rust converters out there.

the best ones are kinda pricey but it only takes a tiny amount to do the job, don't compare it to paint

read the directions before you buy it

extremely tough paint.
yes, it's not cheap, but well worth it. use the cleaner and metal etcher they got for best results.
when i had my crew ripped apart i did the frame susp, gas tanks, pretty much everything. also did the bottom of the cab and box with it. ten yrs of off/on road and practically no chips or re-rust probs- only place it wears off of is the leaf springs.
i put down 2 coats of por 15 and 2 coats of por chassis black over it. ten yrs in and if i took some soap and a sponge it would clean up like new, but i just pressure wash the underside.

Thats what I am planning. The chassis, underside of the cab and all suspension parts. Billibob, I am not looking for a rust converter, I am looking for a coating to prevent rust from forming and keeping my undercarriage black for years! It's funny, my 2011 JKU had 300,000 km on it, and the bottom of that one was black with minimal rust on the chassis and suspension, my 2014 is pretty orange looking now with even some minimal rust popping out on body seams. I am guessing Jeep cheaped out on coatings as they moved along to make more profit.

when i was a diver out on the oil rigs in the gulf of mexico, i was always watching how the deck hands out there handled the never ending problem of rust. i ran across several different types of rust converters being used and i would go home and try them on my rusted equipment. the best converter would have rust bubbling under it in less than a year. i ran across the POR 15 and decided to use it on my excavator in the cab area and floor pan. the stuff is very thin and a little goes a long way. i used it solo and didn't apply a top coat afterward and after 3-4 years, i did see some rust start to pop thru it in places. it stays outside constantly and isnt protected, and with it being in the hot humid swamps with the salt from the Gulf in the air...i figure that is pretty good. short of sandblasting to bare metal, i think the POR 15 is pretty good.
being here on the coast, there are many shipyards and a lot of industrial supplies. years back i bought an industrial grade zinc primer which was recommended to go directly over rust. i used it to paint the frame of an enclosed cargo trailer i have and it has been close to 9 years now and the primer looks new with zero rust popping thru. i left that primer bare and didnt top coat it and its still pristine. so basically i use the POR 15 for cosmetic areas that dont get abuse and for things like frames of trailers, etc, i go with the heavy zinc primer....thats what they use on ship hulls, so its made to last harsh environments and the prep is nothing more than oil/grease removal and a light sanding or wire brushing to remove the heavy rust.

Is it a spray or roll on?

POR15 is awesome, but it goes on like water. IF you get it on something, you better hope thats where you want it to be!

POR15 is great but has one drawback. It is not UV protected and breaks down here in Colorado if exposed to sunlight. I found a product I like better about 20 years ago. It is much like POR15 but includes UV. It is a Marine rated product from Top Secret Coatings. It is available in about a hundred colors and is thin but covers like POR15. Check out the website. By the way, they started by making Military grade paints and are no fly by night operation.

Like POR-15, it is a moisture catalyzing paint. Wear gloves. If you get it on your hands, you have about a minute to use some lacquer thinner to get it off or you will be taking off the skin to get rid of it. Don't bother asking me how I know ;-)

Here in Colorado the POR15 goes chalky on bumpers and skids.
