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.

Excellent product to use n marine environments
Excellent waterproof product for sealing safety glass into stainless steel frames for boat portals. Stays soft and pliable in very cold temps. I tested this down to -10 F and still extremely adhesive and pliable. Easy to work with.

Heads up
Fair warning best to use it when it’s cold. Clean area before you use it. I like it so far but I’m concerned if it melts I will let you know if anything changes.

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 product, well packaged
Bought this to replace a similar item that arrived in a much bigger kit for a self-build shed which had melted into a sticky mess during shipping. This product was well packaged , even to the point of being enclosed in a circle of polystyrene to stop it rattling around inside the box, so it arrived in perfect shape. It unrolled easily and smoothly for application - best if one person holds the roll and the other applies it to the surface as it is very, very sticky which you want it to be for its purpose! It was easy to cut with scissors - best done with the paper backing still on. Would recommend.
