Re: Temporary Screw/Bolt Hole Sealant
cas, you've got it backwards.
The expensive 3M Silver is not expensive, and it is not top-dollar. In fact, it is bottom dollar, it is the CHEAPEST masking tape for that job.
Like the distorted Amazon picture, which seems to show a 2" wide roll of duct tape, not the 1"x60yd. wide-core roll of this product, you've got some facts mixed up.
If you use genuine metal duct tape (which is what the metal tape is) rather than the "duck" or cloth "duct" tape and don't accidentally buy the big cheap roll of silver MYLAR tape that is sold in the same HVAC section...that stuff is expensive, and it only lays flat. You can patch lots of holes in a flat deck with it, but you can't MASK and run it around curved objects, the way a crepe paper masking tape is used. And you can't tear aluminum tape with your fingernails, so now you're scissoring.
If you want a crepe paper making tape that can be left out in the weather for a month without problems, the 3M product is arguably the CHEAPEST product that will do that job. And possibly the wrong product, at any price, for other jobs.
If you run out of pb&j for the kids' lunch, sure, you can spread caviar on the bread. That might also be a waste of the wrong product.
