Patch Filler and Seam Sealer is, quite literally POR-15 in a tube. Like the original POR-15, it dries as hard as a rock, while remaining flexible. Once dry, Patch Filler and Seam Sealer is totally impervious to solvents and fuels. It's so tough it strengthens weakened metal surfaces that have nearly rusted away. Patch Filler and Seam Sealer won't absorb moisture and swell like conventional body fillers and seam sealers. Try it for yourself and see if you don't agree that it is indeed Incredible.
