Here’s an interesting new marketing idea for tape that sticks to itself only: sell it as a “disposable clamp.” The manufacturer, QuikFix, claims that their Quick Clamp Wrap leaves no adhesive on either raw of finished wood. While I can’t imagine this actually replacing a real clamp, it might be handy when there’s really no other way to hold two items together.
A clear “barrier tape” separates the tape from itself in the roll, and you discard it as you unroll the tape to apply it. QuikFix says you just press the tape together, and after the glue dries, you just cut it free to remove it. It looks like it might prove useful as tape as well: it’s good from -60 degrees F to 500 degrees F, creates a permanent air and water tight seal, and insulates a bit as well.
The bad news: it’s a bit pricey. Rocker offers it at $6.50 for a 10′ roll.
