Seals great
I used this to seal a third brake light on a ‘13 Outback to replace the OEM crappy gasket which caused water to leak into car; it seems to be a common problem. I got the 3/8 thickness knowing it was too thick for my application but I also knew it could be stretched and rolled thinner. I stretched and laid butyl around the light’s gasket surface and around both bolt holes, then slowly pressed into place, pushed all around to seat and slowly tightened nuts. The description says made of US materials, the box says made in China. The butyl separated from the paper without issue but I bet if it gets real hot, separation could be a problem. We got a good rain last night and it’s dry inside my Subaru. So far, so good on the seal…I’m sure I’ll use this again to seal out water.

Good butyl
Used this for resealing headlights, it worked great. One box had plenty for both headlights and it is nice and thick butyl. Heated up and pressed the lens on and sealed perfectly just like original, haven’t had any water leak into the headlight. If I ever need to get into the headlight again I’ll be able to heat it up and pull apart fairly easily.

Seems to work in sealing auto lights
Used this to help give a secondary seal over the 3rd brake light on a Ram truck. Easily pliable, stretched it to the desired thickness and pressed onto the light. Worked perfect. Now to see if it will droop or unsealed. So far so good

Great ready to use butyl sealant tape and is plenty thick
Bought this stuff to fix up (or rather rebuild) a nonexistent vapor barrier in my car door. Seems that the previous owner ripped out the vapor barrier and never replaced it. So I bought this butyl tape and some vapor barrier material from home depot (the stuff in large rolls for homes) and got to work. Trimmed the vapor barrier to the shape of the door, use this butyl tape around the edges and no more condensation on the window when it rains! This tape is wonderful. Sticks very well to both the metal of the door and the vapor barrier material. Gave me an OEM finish for the vapor barriers. Only bit of info to note is that 1) the butyl tape is very very sticky and 2) you can stretch it out a bit when applying it. As for point 1), just note that this butyl tape will stick to anything. As such I do not recommend you apply this stuff without gloves. And if at all possible, handle it and stick it with the wax paper backing that they have lining the thick roll of butyl. Also if you get this butyl tape bunched up on itself, it will almost certainly not unwind from that. So be careful as it is very very sticky. As for point 2) I found the best result was to stretch the butyl tape so it became slightly thinner before applying it to my car door. This not only allowed me to do two doors using about less than a half of the roll, but i found the slightly thinner gauge was more appropriate for the door. Regardless, whether you stretch it out or not, the tape works great, but by stretching it out you can save a bit of material for the next time.
