## Overview

POR-15 Patch is a 4 oz high-viscosity filler and seam sealer designed to permanently repair holes and cracks in steel, wood, and some plastics. It cures to a rock-hard, waterproof finish resistant to fuels and solvents, adding strength to weakened metal. Ideal for professional and DIY use, it fully cures in up to 96 hours and provides a moisture-proof, durable seal that outperforms conventional fillers.

## Description

POR-15 is a rust-preventive paint designed for application directly on rusted or seasoned metal surfaces. It dries to a rock-hard, non-porous finish that won't chip, crack, or peel, and it prevents rust from re-occurring by protecting metal from further exposure to moisture.

## Features

- ✅ WHY CHOOSE POR-15 PATCH? - POR-15 Patch is quite literally POR-15 Rust Preventive Coating in a tube. Remains flexible while working and dries rock hard becoming impervious to fuels and solvents. It’s so tough it may actually add strength to weakened metal!
- ✅ ALL PURPOSE PATCH – While wearing protective gloves - POR-15 Patch must be applied to dry surfaces only. Dries to touch in 4-6 hours but full cure may take up to 96 hours depending on thickness applied. Once dry, POR-15 Patch cannot be removed by any solvent. Keep cap and threads clean before resealing. POR-15 Patch dries to a rock-hard finish and sanding is very difficult, so we don’t recommend use on car exterior parts if a cosmetic finish is desired.
- ✅ PERMANENTLY SEALS SEAMS - Unlike conventional body fillers, POR-15 Patch won’t absorb moisture and swell. It dries to a rock-hard finish that won’t crack or chip & cannot be removed by any solvent for a permanent seal.
- ✅ WHEN DO I NEED THIS? – Patch permanently seals loose furniture joints, patches holes in steel, wood, and some plastics, fix fuel tanks & floor pans, bond steel, and repair concrete & cinder blocks. – You name it, POR015 Patch offers versatility across all your projects.
- ✅ OUR SATISFACTION COMMITMENT - At POR-15 we strive to bring the ultimate in rust prevention. Known for the unbeatable 3-step stop rust system, POR-15 is trusted by DIY & Professionals. We are committed to innovation, quality control, and excellent customer service.

## Questions & Answers

**Q: The description in the pic says "...it dries as hard as a rock, remains flexible". Does anyone see a problem with that? How can this product be both?**
A: That claim is 100% true. It's the consistency of pudding for example. Can be drilled, tapped or sanded etc. Also makes a great adhesive when mounting parts. Dries rock hard, but does in fact remain a flexible product. Not flexible like a cured silicone, but can be bent or beat on with a hammer and remains intact. Very good product and that comes from personal use.

**Q: Would this be okay to use for small rust hole in fender?**
A: Yes...I repaired more than a few 1" holes in my VW Bug floor pan.  This will stick to rust, but make sure to sand the surface, thoroughly clean all grease,oil wax & remove anything loose.  For my 1" holes, I backed the holes with Por 15 "Power Mesh" reinforcing fabric.  You could also use fiberglass fabric.  Go to por15.com  they have instructions on the use of all products.

**Q: Will the open tube dry up like the paint?**
A: Hi yes but if you clean the threads off with thinner it will make it easer to take the cap back off, it only gets hard in the tip so I use my drill press to open the tube back up in the tip just take the cap off and easy the drill press down in to the tips and the hard epoxy will come out and you can use the rest of it.

**Q: Do i need to use this before the rust preventive paint? should i apply it after? thanks in advance**
A: You can apply the POR patch after applying the rust preventative paint.
