ST30 is a fantastic tape that gives weeks of hold.

My only difficulty with it is that it can be difficult to get off. I mean, how do you get your solvent "under" the tape? The tape is pretty much waterproof. So you can apply solvent around the edges, but in the end you end up pulling the tape of your skin and this can leave the skin a little raw. Especially if you are using it week after week on the same areas. So I had to give it a rest as my scalp started getting a little red.

But now I'm using it again with no problems, just sometimes I move it around and don't use it on the same areas all the time.
