✅ 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.
