## Overview

POR-15 Rust Preventive Coating is a professional-grade, moisture-cured protective paint that creates an impenetrable, non-porous barrier against rust and corrosion. Ideal for automotive, industrial, marine, and construction use, it bonds to multiple surfaces including metal, wood, and concrete. Its semi-gloss black finish resists chipping and cracking, ensuring long-lasting protection. Trusted by experts and DIY enthusiasts, POR-15 requires proper surface prep and topcoating for UV exposure to deliver permanent rust defense.

## 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.

## Features

- ✅ WHY CHOOSE POR-15 RUST PREVENTIVE COATING – POR-15 is the gold standard in high performance coatings. Trusted by DIY and professionals to stop rust permanently by forming an impenetrable barrier that protects a variety of surfaces from water, chemicals, salt, corrosive contaminants and everyday wear and tear. No other paint, coating, or even powder coat can match POR-15 Rust Preventive Coating when applied using the 3-Step Stop Rust System.
- ✅ CURED BY MOISTURE – The secret strength lies in the curing process. Unlike most paints that dry through evaporation, POR-15 Rust Preventive Coating dries faster when moisture is present. It has the opposite chemistry of ordinary paints. Once cured, the coating forms an indestructible, hammer tough finish.
- ✅ APPLICATION - Remove grease, oil, and other foreign substances using POR-15 water-based Cleaner Degreaser followed with POR-15 Metal Prep to etch the surface and neutralize rust. Stir POR-15 Rust Preventive Coating thoroughly, DO NOT SHAKE. Always apply thin coats, minimum of two. May be recoated or top coated when dry to the touch, typically 2 to 5 hours. Topcoat when surface will have exposure to UV light.

## 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.
