POR-15 Patch - Black 4 oz - Filler & Seam ...

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.
