Shop with confidence. If it’s not working out, you can return it (consumables, electronics, undergarments and swimwear excluded).
Really. If it's not up to snuff after you use it (a couple times) you can still bring it back. It lasts longer than 30 days, but not forever. We'll be fair about it.


McNett’s seam sealer cures to a flexible urethane rubber, sticks well, and lasts a long time. It also works well as an adhesive to glue on repair fabrics. Moisture speeds curing. Use sparingly as a thin film for best effectiveness. Store in the freezer once opened.
