POR-15 Patch is a thick, tube-applied version of the POR-15 Rust Preventive Coating designed for filling seams and holes. It cures to a hard, flexible finish that resists fuels, solvents, and moisture. Unlike conventional body fillers, POR-15 Patch may reinforce weakened metal and won't swell. This product can be used on steel, wood, and some plastics.
Application: POR-15 Patch must be applied to dry surfaces only. Wear protective gloves while using. Remove from skin immediately with POR-15 Solvent or lacquer thinner to prevent temporary staining. 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 re-sealing. Recap tube immediately after application. 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.
