Review: Nice and easy to use. Works well - It’s as described. Pretty pliable and soft but not like putty. Stretches easily it should work for your needs were it is required for this product. Metal to metal on my old car works fine. Weather strip Chanel tracks ect. Came in a nice roll. Packing was very nice. Easy to use product. Cool area I used it in around 60 degrees. No mess.
Review: If your unsure. It's definitely worth it - About this to install a fan in the bathroom of my camper. I instantly tested to see if it was waterproof before I added my Henry's tropicool sealant on top. It worked perfect I left the water hose on the roof with water hitting Butly tape directly no water penetration whatsoever before I even put the screws to tighten it down this stuff is amazing. It's incredibly sticky and the thickness was exactly as described
