Were gonna see some new stuff coming out shortly. 3m was the first to develop a "No residue" Duct tape that we have been testing for a 2 years now. It can be left in direct sun for up to 6 months without leaving residue. (its on the market already) it is a great improvement to the Shurtape PC 667
Shurtape is not far behind in developing high strength no residue tapes so i assume they will implement this to the gaffers (PC 628) tape as well. Recently alot of engineers use the (FP 227) for marking there mic's and such. Its a paper based tape so its not rubbery feeling but has a very strong adhesive and removes clean on most substrates.
