## Overview

POR-15 Rust Preventive Coating is a professional-grade, semi-gloss black protective paint that chemically bonds to rusted metal, creating a rock-hard, non-porous barrier that permanently stops rust and corrosion. Designed for direct application on prepped metal surfaces, it resists chipping, cracking, and moisture exposure, making it the go-to solution for automotive and industrial rust protection.

## Description

POR-15 Rust Preventive Coating is the Only Product that REALLY Stops Rust Permanently! POR-15 Rust Preventive Coating is designed for application directly on prepped rusted, sandblasted, and seasoned metal surfaces. It dries to a rock-hard, non-porous finish that won’t chip, crack, or peel, and it prevents rust from recurring by protecting metal from further exposure to moisture. POR-15 Rust Preventive Coating is sensitive to UV light and must be top coated when prolonged exposure to sunlight is possible. Top coating is not required for areas not exposed to sunlight.

Review: Please READ!!! Save yourself and UNDERSTAND!!! This product is AMAZING!!! First off painting anything is all about PREP work! Everything must sanded/scuffed, cleaned, degreased, washed off with water, dry, decent weather conditions if your outside, your work should be taped off, covered in plastic or newspaper and follow the directions on the cans! My experience with these products…ALL 5 star!! The cleaner/degreaser ***** The cleaner isn’t some harsh chemicals that burns your hands! It doesn’t smell and works amazing! Get a spray bottle and light scrub brush and scrub your work area. Dilute it with water 4:1. The metal prep/rust inhibitor ***** If your work piece has rust USE THIS! After sanding/cleaning the area and washing it off use this. It will take light rust (that maybe you couldn’t sand all of it away) and chemically breakdown the “rust” properties turning it back into its original metal state. Which then is a paintable clean surface. Listen Peoples, rust is like a cancer, ither cut it out, put in replacement metal or use this, and FOLLOW directions!!! It works!!! Read the DIRECTIONS!! The Por-15 paint*****The BEST PAINT!!! This paint is some serious stuff! It gets rock hard! KEEP THE CAN AND LID PERFECTLY CLEAN, the lid will seal itself shut if there’s ANY PAINT ON THE RIM!!! (That’s why they sell 6packs of small cans) and don’t paint outta the can, poor into something else. Stir the cans!!!! There’s 3/8inch chemicals at the bottom of the can of you don’t stir you’ll hit the bottom and be like”ohhhh what’s this”, oppps!!!! This paint will harden like steel it’s AMAZING STUFF!!! It’s like epoxy, but thinner.(the longer the can is exposed to the air/open the thicker it gets fast!!) When you use this paint you gotta be quick, in a rhythm and can’t stop. At this point everything should be ready for paint. If your using the topcoat paint as well, the topcoat goes on BEST RATE after this drys to “finger drag”. Meaning when you touch the painted surface it doesn’t stick to your finger, and you can drag your finger over it without removing any paint. Once at this point topcoat it RATE AWAY! Don’t wait because you’ll have to sand it, the topcoat adheres BEST when the por-15 paint is finger drag. The topcoat fills in all the imperfections the paint missed. BE heavy, don’t stretch these paints out, (small roller works the best) The topcoat smooths everything to a beautiful finish. THE PAINT AND TOPCOAT ARE NOT THE SAME!!!! They are totally different!!!!!! If you use the topcoat only that’s fine I guess but it’s no WAY near protected unless you use the Por-15 paint then topcoat. The paint hardens like steel, the topcoat does not harden the same way!!!! They are totally different!!! Yes it dries, but it’s just different. It says DTM on the can(directly to metal) and I’m sure you can only use the topcoat but if you want SERIOUS protection USE THE PAINT and TOPCOAT. If your only using one of them I would choose the paint over the topcoat. I restored a truck frame using these products. It’s very time consuming, and prep work!!! But WOW IT WORKED FLAWLESSLY AND WAS WORTH THE TIME!!! If you buy a can and paint over a completely rusted out item without prepping it, don’t expect a miracle. That paint hardens so hard the metal will probably dissolve and the POR paint will be holding it together it’s that strong lol. The people reading this will understand… Por-15 actually surprised me!!! I always used Rust oleum, which is good stuff but I’m a POR believer!!! There stuff is pro!!! I didn’t get a chance to use the primer, but again the key is after painting the rust protection paint, finger drag and topcoat heavy rate away and it’s smooth like butter…YOU DONT HAVE TO SPRAY IT, if you do my research says get POR15 solvent!!! CHEERS! good luck!!!
Review: Have used POR15 for the past year and painted on some rust areas that were developing. Did my rear and front bumper where the paint was starting to fade and starting to show some rust as well. What I like about POR, you can brush this on and it levels out like as if you sprayed it on .... Even though it's a bit pricy for a large project ... I have to say its worth the price on overall looks and finish as well as rust protection. Great protective product for those in salt areas. Helps protect your side panels that are starting to develop rust areas... Got to clean really good the rust area then use acetone to remove any oils, dust or rust particles. Then brush on POR .. you'll save your metal on your truck or car easy... and can paint over it with color match paint yet having rust protection for a very very long time.. I highly recommend buying POR-15

## Questions & Answers

**Q: can you paint over this product? which paint is best latex or oil based.  i am looking to use this on a rusting dive stand.**
A: I have used Por-15 on an extensive restoration of a car.  It can be painted over, but you really want to make sure you get your primer on while Por-15 is still slightly tacky.  this will allow the primer and then paint to stick better.  it is UV sensitive and will change colors if it is exposed to the sun.  On my project, I used it primarily under the car or in areas where there will be minimal or no UV exposure.

**Q: whats the difference between this and the black por 15 ? dose it stop and protect the same?**
A: This is a top coat for por15. Por 15 offers very little uv protection so if you paint something that is going to be out in the sun you have to paint over the por 15 with a por 15 top coat.

**Q: how much would it take to cover a entire 1/2 ton truck? would a gallon do 2 coats?**
A: I used a spray-gun to do the undercarriage on my Vanagon and I finished with 1/2 gallon left. If you brush it than one gallon is more than enough for your truck. Don't get it on your skin! Took me 2 weeks to get it off. This stuff is awesome.

**Q: Does the por 15 clear need to have a top coat? If so what would that be?**
A: You should use a top coat on any of the POR-15 rust preventative paints. You can use any automotive paint as a top coat.

Very nice product! Works as advertised! When wet it is very shiny but it dries flat and the wife says it looks a lot like a nice spray on bedliner.
