Sealant Tape B1+ Silver 4 inch x 50 feet

Great product. Best deal on amazon in this category. Highly recommend.

This stuff is very easy to use and durable. I used it to line the inside of my ‘through the outside wall’ dog door. Stopped the drafts!

This is a decent waterproof aluminum tape. The aluminum outer layer adds durability and weather resistance benefits over just tapes that are just rubber. The adhesive layer is textured, which is not something I'm used to, and not sure if it is a benefit. The adhesive is strong, and is so far holding up to our uses. The backing comes away easier than most butyl tapes I've used, which makes working with this much nicer. It is a bit pricey, but the extra aluminum layer does warrant a bit of a premium

If you have a Camper and it’s starting to leak, I recommend this stuff I mean it works really really well see I live in my camper and my pop out had this leak that would not stop and I could not find it so I was given two rolls of this tape and bought one and I just made a whole new roof out of the stuff and the other day we had a torrential downpour hood lasted for like eight hours not a drop of water got in my camper

Suuuuuuuuuper sticky tape!!!
