POR-15 anyone use?

I have a 1961 F100 that has some serious surface rust areas. Nothing has eaten through the metal but its bad. I am looking to stop this flat and not have to worry about it. This POR-15 seems to be good stuff but anyone on the forum have any experience with the stuff?

IIRC, POR 15 is not UV resistant, so make sure that any POR 15-coated areas that are exposed to the sun are painted over.

It works good, but it does not like the sun. It MUST be topcoated. You could also "kill" the rust with any number of products sold for that. I like to use Ospho. Sold at paint stores.
I think most of these products need to be topcoated.

Iíve used it on old boat trailers, as well as XO-Rust. Both have done a great job. No rust through after ~7 years.

The other posts are correct. Both products must be topcoated for use in direct UV applications.

Yeah I was gonna topcoat with some of Blackcote. After priming and such. The paint won't be anywhere near perfect but will be a vast improvment over what is on there now and won't rust.

i've used por, the mercedesstore.com version (rebranded por15, i dont care what those people claim), and rust bullet.

with any of these products, follow their directions which means that you should buy their products. ill tell you from experience that if you dont, the stuff won't last. i recall their treament is something like a 3 step process. its on their website. the 4th step is for areas exposed to UV rays, so yes, you need to top coat.

Great product, but remember, their slogan is no idle boast--"We know what PERMANENT means"

Wear gloves, or you will wear POR 15 for a long time.

I used it on my exhaust pipes. It semed to work really well. I primed and painted after that but have not been back under the car yet this spring to see what it looks like. I came highly recommended from a guy who sells to bodyshops.

WEAR GLOVES, OLD CLOTHES AND GOGGLES.

I have used POR-15 since about '88. It has held up. They have added some prep materials since then. I have used their wash and metal prep too. I buy the small cans is a six pack to keep thing fresh. If you have a large area, then buy the large can. I put a piece of Saran wrap between the lid and can to help seal it, if there is some left.
I think you need to do two or three coats of it, about 2 hours apart. Then you need to prime it about 2 hours latter when still sticky. They have come out with different formulas since I used it last.

Used it last year on the wheel arches on my E430. So far, it has held almost all the rust back all through the winter. Usual paint and primer would not have. So, I like it thus far...seems to work.

Ditto the gloves.

I use it a lot. The "six-pack" tip is a great one.

"Permanent" isn't the word for the stuff. I repaired some rust on a wheel well. I didn't pay attention to where I had placed a jack stand and now I have a jack stand in a perpetual "full up" position.

I have heard the POR-15 is basically like CA or super glue. So it does a good job of sticking thing together.

Man, that is so depressing to read about rust on a 1998 vehicle.

My 89 260E (may she rest in peace) had not a trace of rust. In a few weeks I will be using the POR-15 kit to treat three areas of my 95 E320. I too can't believe a 98 MB has rust.

Remember that if you need to pee during an application session.
