The adhesive itself is barely any better than standard duct tape, which isn't saying much.

Absolutely NOT stronger than good duct tape, Used on poll cover patching, duck tape takes few years to fall apart , this one came off deteriorated in one season in most parts.

The one thing I did notice is the adhesive does not seem as strong as duct tape.

So if you have some enormously tough job that duct tape can't handle, think of this tape

Best duct tape ive ever used!

The 1.88 in x 20 yd roll of tape is better than the very good duct tape we used before

However, the adhesive is not as strong as duct tape.

How does this get to be 10 times as strong as duct tape and how would I prove it
