For years I've been using 3M duct tape for clamping thin moldings etc. I like it because it stretches, so a reasonable amount of pressure can be applied on thin wood. Lately, I've run into a problem - the tape doesn't stick. It's fine when first applied, but checking on it a few minutes later, it has come loose. I tried a couple of new rolls with the same result. I've tried in on other surfaces, like metal, and again it comes loose. I've given up on using it and hope someone can lead me to a better tape - one that will stay stuck.
