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.

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!

This is an amazing product! First time user of the product and it is simply amazing. I used it as a base for my rock sliders on my off-roader. Prepped and cleaned the sliders down shiny bare metal, etched and primed then applied the POR15. A little goes a long way oddly enough. It is the consistency of slightly thinned syrup. I brushed it on, it self leveled and the brush strokes disappeared and it dried to hard epoxy like she’ll. I had to scuff it up with sandpaper and coated that with spray on bed liner. The POR15 dries perfectly smooth as long as you do not over apply the product. Like I said I scuffed the gloss finish, and applied spray bedliner and it looks awesome. I waited 4 days for the bed liner to cure and hit the trail. A few scuffs and scrapes and one good scrape, which is what the sliders are for and it was easy to use a small brush after cleaning and dabbed some POR15 back on the scraped area and agin it self leveled and I hit it with the rattle can of bed liner. Blended in excellently and a few areas the bedliner scuffed but the POR15 held strong. Easy to touch up with the rattle can and the POR15 was as hard as nails. Very impressed and ordered some more to redo the skid plates and rear shin guards. I’m going g to use POR15 to prevent rust and encapsulate the metal protection on my off-roader. I’m sold, can’t believe this stuff sticks like it does and is as hard as it is when dried. If you have never used it, I encourage you to do so. I should have taken pictures. I thought it would peel and scrape off but it is as hard as nails, even rubbing against rocks on sliders. It is frickin’ awesome!

Excellent

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.
