tho E tape may sag in heat, 3M if stretched over a prepared clean surface then pulled tight across itself looping around tubing and cage feet doesnot sagout.
33 works. There are heavier 3M tapes.
and off course, color tapes.
white on white, blue on white, green on blue....
color 3M I used was thinner than 33, better for waterproofing junctions.
