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.

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

Easy to use and seals well, great product!
Great product and flexible enough to do the sealant jobs I needed. I ought for my RV to install some additional solar panels and place under my slam lock catch that had a leak. I can already see a few other places I can use it so imagine it will just stay in my camper for some emergency situations.

If your looking for something that sticks and lasts a long time THIS butyl tape is the answer to all those problems! It's thick but yet plyable kind of like playdough it's waterproof and heat proof and man does it LAST FOREVER! Just make sure you don't get it anywhere you don't want because seriously it LASTS FOREVER lol and it's not just good for rv use we have used it in many different ways from household to automotive to arts and crafts!

Durable waterproofing sealer for DIY Projects
Great roll of butyl tape, gets the job done at an affordable price. I used the tape to seal cracks around my truck’s camper shell window. Stays sticky, easily moldable, waterproof. The tape is thick and durable.

Great sealing tape. Same price and double the product of the local HW store.

This is a pricey but efficient product for eliminating leaks in metal roofs. I couldn't stop water dripping through the aluminum Yardistry gazebo roof, no matter what kind of sealant I used. Was applying new specialized roofing products two seasons in a row until I read about this tape. It was not easy to apply but it seemingly finally resolved the issue. If I ever have to assemble a metal gazebo roof again, I will install this product from the get-go.
