  • It works!
Size: 2 Pack Color: White Fast Curing
Easy to use and tacky to stay where it's applied.

  • Repaired my teardrop after a bear attack
Size: 2 Pack Color: Gray
A large black bear tried everything he could to get into my teardrop on a recent visit to the Smoky Mountains. In the process, he tore off the waterproof rubber flashing that covers the hinge on the back hatch. What a mess! After removing all the old material and caulking, I installed a new one with this sealant and feel confident it will do the job. It's the exact same compound recommended by NuCamp, the mfr of my Silver Shadow. One note, this stuff is pretty thin and very gooey out of the tube, but cleans up great with alcohol (I used pure 200 proof made for indoor fire pits). It dries in 24 hours with a similar rubbery consistency to silicone which is exactly what you want on a seam that has movement. If I have any issues I will update this review. For now, 5 stars! ... show more

Works perfe t. No other parts required. Took 15 minutes to do and fixed numerous problems. Old valve turned so hard and was half blocked by twisted up O rings. Water pressure is a little better and camper pump works as it should too. VeryHappy!

  • Good product no water in my cab now
Size: 2 Pack Color: White Fast Curing
Doing a restoration on my 1970 GMC had water leaking between the kick panel where it meets the floor. Used this seam sealer it was completely dry and water tight the next morning. It's been in the rain for a week still dry I'd buy again and I recommend the product.
