POR-15 Rust Preventive Coating, Stop Rust and Corrosion Permanently, Anti-rust, Non-porous Protective Barrier, 32 Fluid Ounces, Silver

The price may seem high but this stuff is quality. Make sure to wear gloves and ensure the fumes are vented because this stuff doesnt come off of anything (clothes, skin, etc.) i did a full bed off repair on my 2002 tacoma and after welding repairs i prepped and coated the entire thing with por15 (silver in the bed black underneath) 2 quart size cans did an entire tacoma bed inside and under. After it dried i was very happy with it. This was the 100% most recommended product to me in order to prevent rust/ rot in prepped and/or repaired metal here in upstate NY

Amazing stuff, used it for over a decade on countless projects. Silver contains metallic particles, so it will actually fill in pits and strengthen a weak-from-rust floor pan for example. Dries harder than a teenager in a strip club, in 2-6 hours, unlike products like Tremclad that can take many days to cure fully.That also means you have a limited window of time to recoat it; do a second coat as soon as it’s not tacky but before it’s cured completely. Misting with water helps cure it faster if you need to; it’s hardened by moisture and gets tougher over time!It’s not the most aesthetically pleasing paint, it’s inconsistent visually, so if you want something to look good you can spray a light coat of regular paint or primer over it, again BEFORE it’s fully cured.Do NOT get it on your skin or clothes, nothing will remove it except POR 15’s own special thinner, or time.

This product is incredibly awesome. Looks great and tough.

Very happy with purchase and price

Hey gearheads!!I am quick to complain about products that do not live up to claims, but in this case I used a product which exceeded my expectations by far: Por-15.Our Saab is mostly rust free except for the frame rails in the front clip, and the rear crossmember (the crossmember is replaceable... /if/ I want to do a full rear suspension rebuild). Last winter before I put the Saab back on the road (a part was on backorder) I found the torque box joints in the front had thick flaking surface rust but now just seven months later the whole front frame is rusting. most "rust converter" paints are frauds and do not work. Por-15 is a multi-step system where you clean the metal with degreaser (I skipped that step as the frame only had a couple of tiny greasy spots on it), scrape off any flaking paint and loose rust, then you apply a metal prep solution that both etches and thinly plates any bare metal and converts rust into a different iron oxide forming a patina, and then you apply the rust preventer to stop the rusting process.Well I did the etching step today, agitating it with a steel brush, washed it and blew off the excess water with a leaf blower, then just went out to check it after it had time to dry. I was amazed; everywhere I had agitated it with the steel brush, the rust had either been removed down to bare metal, and where the rust was slightly deeper it was converted to a black oxide (a patina), and the bare metal sections had a very thin but visible zinc coating. This stuff actually works. and once the rust was removed I found the frame is perfectly fine.Because it has spread though I am taking the front end off to treat the sections covered by the bumper and spoiler panels then I will get a paint sprayer and paint it.if you're restoring a bike or car where rust is in the early enough stages that the metal is still solid, try Por 15. if you follow the steps like I did that are provided in reviews by people who have had good luck with it, the results will blow you away. Not only will I be able to get another winter or two out of the Saab but it will probably last a long time for whomever I give it to. That is assuming of course the frame isn't also rusting from the inside out but I have an idea on how to address that with a pressure washer, Por 15, and fluid film.for the rust preventer I chose silver because it provides more pinhole hole filling capability but fortunately that was unnecessary because I caught the rust early enough.Follow directions and you will be pleased. Be sure to agitate it and reapply the metal prep many times, keeping the parts you are treating completely soaked.
