I've also been using it ever since I built my first wheels for the then new narrow (and high pressure) clincher rims (Rigida 13-19 red labels) back around 1975. The rear wheel from back then is still in good shape and still has the original electrical tape in it after 35 years. Maybe there would be some glue residue, but I don't see that as a big issue - why would I ever need to replace the tape; and if I did I'd just put another layer of tape over the old glue. Usually the rim tape doesn't get touched until the rim wears out due to brake wear. At that point I remove the tape so I can move the spokes over to a replacement rim. If there's some glue residue I don't care since I'm throwing the old rim out anyway.
