Review on POR-15 Patch - 4 oz White Filler & Seam Sealer for Steel, 🔧 Wood, and Plastics - Ultimate Adhesive to Strengthen Weakened Metal and Patch Holes and Cracks by Larry Morris

Wow! Applies and dries absolutely BLACK. Brilliant when dry. Hard as a rock. Perfect for filling in my sloppy welds (no comment) when I paint over. I used it to fill the end of a 1/4" x 3/4" pipe on a project as welding would have been a project in itself and it was by far the right answer. Mold-dried, hard and absolutely unbreakable after hardening. Feels hard like steel. After sanding I painted the project (POR-15) and the pipe ends looked great as part of the steel. Warning - wear gloves like POR-15, it will stay on our hands for a while. Long time.
