NAPA, when I got the expansion valve there, I asked about this tar-tape and the guy couldn't find anything in the inventory, then Mel (the owner) over heard what I was looking for and he said he had a box of dumdum tape that he ordered for a guy a few yrs ago and was never picked up. Mel went to the back & after a few minutes he found it but said I had to buy the roll (25') It was waxpaper covering the tar. On the NAPA receipt, it shows "misc tape" This is a very old NAPA location so who knows what other stuff is stashed in there warehouse........
I used maybe 1.5' to fix up the 2 tubes on the evaporator box but I can see other places to use it (under the dash possibly) If you want a few feet, no problem!
