You should be in the nuclear power business like I've beenfor the past 20 or so years, then you could use all the RED (we're currently using POLYKEN)DUCT tape that you would want (It all started with the DUCT TAPE we used in the Nuclear Navy - it was some of the strongest DUCT TAPE that I ever used). Although, the people we have to do our radiography here at the plant use more DUCT TAPE than any one else for the same amount of actual working time by far!!!! Wayne G.
