pretty good adhesion, but not like the high-end stuff (secondskin).

Has a decent weight to it and has very good adhesion to properly prepared

This improves adhesion and makes rolling it easier

Easy to install, good adhesion.

It has excellent adhesion and forms well over irregular surfaces

The adhesion is very good as well, and I found it easy to peel off and put on a slightly different location without it loosing stickiness

Excellent adhesion

Used a hard small roller to enhance adhesion.

It installs well, has great adhesion, only tore when I tried to make it fit in an impossible curve/crease (my bad)

I purchased this to line the outside of a wooden box I built to contain a Bitcoin miner, as well as to line both sides of 5/8 inch plywood before attaching to the walls and ceiling of the room the fans blow into

The only reason I gave it 4 stars out of 5 is that although good - I wouldn't want to set expectations to high.

My speakers are JBL GX602, and a cheap-o Walmart sub I got as a placeholder while I finish building the real deal
