I frequently use double sided tape when making duplicate parts. Recently my roll of 3M double sided film tape ran out. Unfortunately, 3M didn't put the product number on the cardboard roll. The tape was an acrylic based adhesive with a clear liner the tape is only a few thousandths (.002-.005) of an inch thick. The removable backing was white. It was 1-1/4 wide. I have another project coming where I'm going to need this tape.
I checked my local tape sources and none carry anything except carpet tape which is too thick for my needs.
Anyone have a good source for double sided tape?
