## Description

A high performance coating designed for application directly on rusted or seasoned metal It seals and protects surfaces from water, chemicals, salt, and corrosion

Review: 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!
Review: 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.

Awesome product but read instructions carefully and don't use right out of the can as runs in and around the top will keep you from sealing it back properly for reopening and future use.
