Review on Black POR-15 Patch - 4 oz Filler & Seam Sealer with Ultimate Adhesive Properties - Repairs Holes, Cracks in Steel, Wood, and select Plastics - Reinforces Weakened Metal by Chris Peck

Excellent product. Works the same as the thicker version of the famous POR15 paint. Dries strong. I used this on a '92 Toyota pickup door on the bottom edge where they tend to rot. There were several rusty pinholes poking through the paint. I was debating whether to replace the door, weld on the patch panel, or try this product. I'm so glad I gave this product a try! After scraping off rust and sealant that was no longer holding, I glued a POR patch to the bottom edge of the door. It worked great in place of a seam sealer and dried nice and tight. While new metal would be the preferred and correct repair, I'm sure the door panel will last for many years to come. Note. This product is thick! Hands will strain trying to squeeze it out of the tube, especially when working in cool weather. I would suggest keeping one of those toothpaste rollers handy to make squeezing easier.
