POR-15 Patch Filler and Seam Sealer

The ultimate filler adhesive. Apply right over rust or bare metal.

Fix that seam or channel with POR-15 Patch. For years our customers have asked us for a thicker version of our world famous POR-15 Rust Preventive Coating, to use for filling seams or holes. Here it is! POR-15 Patch is quite literally POR-15 Rust Preventive Coating in a tube, and it dries as hard as a rock, remains flexible, and once dry is totally impervious to fuels and solvents. This rust hole filler is so tough it may actually add strength to weakened metal, and it won’t absorb moisture and swell like conventional body fillers. Try it yourself - this sandable seam sealer is incredible! Patches holes or cracks in steel, wood, and some plastics.

Use it to:

  • Permanently seal seams
  • Repair loose furniture joints
  • Patch holes in steel, wood or some plastics
  • Fix holes in fuel tanks
  • Bond steel to some plastics, wood or concrete
  • Repair concrete and cinder blocks

Sure beats welding for small patch jobs

Have used this product for a number of years to patch small rust holes--up to 1/4" (6mm) with no additional support, and using fiberglass window screen for holes up to double postage stamp size. It's held up in areas subjected to abrasion and moisture (rocker panels, lower doglegs) for several years without any blistering, bubbling or deterioration. Where I would have previously had to cut a small rust spot back to sound metal and then weld in a patch, now I can use POR patch, a little filler (sometimes not even necessary if I apply the patch smoothly) and paint, and the job is done.

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.
