I had a 34 year career with 3M in my hometown. It is a Industrial Tape site. I shipped Acrylic Foam tape everywhere...almost exclusively used in the automotive market. You would be sick if you saw what we sent to the landfill on a daily basis...all widths, all thicknesses. Plenty good for you and I. (Fortunately, employees could by a big roll for a quarter). I am aware that 3M made a product that supposedly held jet aircraft wings together! I don't know off hand what facility produced it. I'm going to run this down and try it on a few plugs. 52Carl...thanks for mentioning...I forgot about it.
