POR-15 Rust Preventive Coating, Stop Rust and Corrosion Permanently, Anti-rust, Non-porous Protective Barrier, 16 Fluid Ounces, Gray

If you want permanent rust proofing then this is the only product out there worth buying, It sets like porcelain and rust will not come back.I have restored a vintage Ferrari with this stuff, a fiat 500 and even coated my old cast drain pipes with it.Use metal prep solution first from por15 before you use this and take care not to get it on your skin as thinners or paint stripper will not remove it and it goes a very long way.I can definitely vouch for this product and I live in Scotland near the se where it rains most of the time.I wouldn't use anything else as rust proofing goes as this is the best there is.

This product is a winner. I used in on a rusted mower deck and it is getting well used and proving quite durable. Best stuff that I've ever used in this application. Highly recommended.

Excellent

Great product. Goes on smooth, dries in 2 hours with a rock hard finish. Used POR 10 years age on a rusted truck chassis, finish still in good condition, no rust. This time on a vintage wrought iron table/ chairs. Wire brushed loose rust, cleaned the set, and Applied POR. Looks great. Cons: pricey product, but goes a long way ( 1 pint for table and 4 chairs) must clean-up spills before product dries or near impossible to remove. Recommend using 2nd container to hold paint for project. If product gets on rim/can lid near impossible to remove later!

Man, this stuff really works. We live in a condo by the beach, and we get salty breezes year round. In my community, most neighbors have hurricane-proof garage doors, which are made of steel, and rust very easily. My garage door was always showing rusting from behind the paint. I had tried rust oleum paint before, but the rust would come right back within a few weeks. Until one neighbor recommended this product to me. One can of POR-15 was more than enough to paint right over all the rusty spots on the door, and it's been almost a year and no new rust has popped up. I'm very satisfied. My only complaint is that the unused portion became solid inside the can very quickly (whithin a couple days of finishing my project). But I guess that’s just the way it is. Other than that, I'm a happy customer!
