Did a great job
The rubber sealant worked perfectly for sealing the frame of the window to the body of my truck. I did have to go back and fill in some places, not the fault of the sealant, just dips in the window channel. Sealed out the water and wind noise

Sticky Weather Barrier
Great product. This is what you need to put the plastic weather barrier back on the door. Scrap the old stuff off and apply a healthy bead of this. Will definitely be using on future projects.

Normal Butyl Rubber sealant, good quality
Applied easily. Gooey as you would expect. Don't get it on anything you don't want it on- but if you want it there, it will stay.Spiderwebs are normal, be careful.

Butyl Rubber Caulk
Purchased several tubes for a large project. The tip seems overly large so you can't apply all of the tube contents. Normal caulk gun seal puncture not long enough unless you remove a third of the tip - which would be a very large application bead. Since I wanted a small bead I used a cabinet-tip screwdriver. Not easy to clean off from my screwdriver. Also the tube-tip seems floppy. One tube blew out the side after 80% used.Once the black goop was applied where I wanted it, it works great. Cure time depends upon applied thickness. After a month it is still adhering to what I applied it on, connecting pieces of rubber, or rubber to steel.

Rubber Butyl Caulk
I really Iike the black butyl color. Almost everything blends well with color black on surfaces. Not as messy as other caulks, adheres well on surfaces, and worth the money spent on them.
