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

Good Stuff, 20 years going strong.

I've been using POR15 and POR Patch for almost 20 years, still owning a vehicle I used it on 19 years ago to fill tiny rust pin holes in a door. Still holding strong on that door. I just used the new "white" version of POR Patch, which I like a lot (white color), to fill some small holes and it still works great..!

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.
