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 Cesar Carter

The product is suitable for filling small holes such as sweat burns. It might be a good way to reinforce rusty old welds, but it's better for smaller jobs and I wouldn't use it as regular seam sealer. I probably wouldn't buy it just to fill holes that could be filled with lime grout, window welds or traditional seam sealer, limiting its use to damaged old panel welds. In this case, be sure to wear gloves. This material will stain your skin for at least a week.
