Very effective-needs care in handling
Almost the consistency of a caulk in warm temperatures-tricky to apply if so. Sticking power is excellent. I can see a variety of uses for this, I already have used it for attaching loose rubber trim back together. Adheres well to metal and plastic. The consistency is very pliable-has to be handled carefully or you can stretch it out of shape very easily, and it sticks to itself completely!

SUPER stickey and seals the screws
Worked great

Works as intended
Worked just how I needed it to seal up my camper door window. If you do like the instructions suggest and put it in the fridge for a couple of hours, it is much easy to handle. Work quickly before it heats back up though.

Works well
Used this to seal a new RV window. The only problem was I had a lot of squeeze out and cleaning it got messy as the butyl is gooey and gets all over the siding. Fortunately a bit of gasoline on a rag cleaned it all up. Otherwise, it definitely did what it's meant to do.

Sticky Stuff for the Jobs That Need Sticky Stuff
This worked well for sealing and sticking things where I needed them. It is very tacky, conforms well, and is useful for automotive and other sealing jobs where regular tape isn't going to cut it. Messy if you aren't careful, but effective. 4 stars.

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

I like it
Very soft compound and very sticky. A little tricky to apply cause if you pull on it it will stretch and thin out. I just hope it stands up to sun and weather.
