Dicor BT-1834-1 Butyl Seal Tape - 1/8" x 3/4" x 30' Repair Tape for RV, Trailer, Motorhome, Window, and Vent Sealing

This stuff is soft and sticky. Just like Bazooka Joe bubble gum. Pliable is another word that comes to mind. The seal will last for years. Sticky on both sides.

Works great for a lot of different reasons

Sealed around newly installed roof vent worked well, no leaks.

Good quality, easy to use

Gooey and works great. Easy clean up with plastic scraper.

Recieved in plastic bag inside box. easy to open and roll kept flat. Roll was in great shape not smashed or all stuck together because it got warm! I wanted gray and didn't realize this was black. But it will work I can cover it with white Dicor self leveling caulk for rubber roof and hide the black tape. The tape is easy to put down when it's kept cool until actual use. Once warm from sun it gets very sticky.

I have been using this stuff to shore up the seams, seals, areas around light fixtures on the outside of my RV. In my opinion, it's perfect, I can shape it like putty in the size and shape I want with my fingers and it goes along and creates a really nice seal. for whatever reason by accident i had silicone spray recently on my hand and that actually helped me a lot in not getting this stuck to my fingers while I was custom molding it to some select areas around the RV. my roof was in generally good shape but this was great for some shady areas that just needed shoring up. For one area on the back window, I applied it to a corner exterior of the window seam in a place where I suspected water was leeching and that problem has been solved, water no longer comes through the back window. That was over two years ago. The picture here is what that looks like about two years later.I cannot comment on how great it is technically. Someone with a degree in materials science can explain why this is apparently a good product for exterior RV uses but as far as I am concerned, it molds on great. I got the gray kind but so what it's a little gray .... I am much more concerned about the quality of the seal and could care less about color. It is also not all that noticeable. I can say now that after a couple years it just kind of looks like grey silly putty but has not been washed away or otherwise compromised.Disclaimer. I am a total amateur at this RV thing and have only nominal or no idea what I am doing but this stuff seems really great, like if you were all off a sudden got some roof leak, this stuff seems like it could be the total bomb.if you think it is sticky to work with, try spraying your hands with a little silicone and it will allow you to mold this stuff without getting it stuck to your handsUPDATE: over a year and a half after doing the repairs with this stuff, the repairs are holding nicely although this picks up a little dirt so some discoloration but that's quite minor compared to a leak

I am giving five stars because the product is good. Problem I have is with the packing from Amazon. I will post the pictures of how they packed it and how it got smashed. They put it in a big box with absolutely no packing. Seems like they’re getting really careless.
