I just pulled the trigger on my 2" roll of Scotch Rubber Mastic tape for field dressing a bleeding engine case. I'll break you off a piece if you come visit. I have 10' and only need one.
I also picked up a new roll of DOT-DOT-C2 Reflective Conspicuity Tape. I cant get enough of this stuff. I have it plastered all over my bike. I need some more to put on the trailer too.
