I tried out Supertape for a week. It worked great, never got gummy like USA Tape did, nor did it have the sharp edges that USA Tape has. It seemed like it might hold for another week without problem, though who can tell with these things for sure without trying? I didn't like the shine, though, and so I sprayed Prothik on it to cover up the shine. My stylist says that I can probably dull the shine by rubbing baby powder into it, but I prefer glue in any case.

If I ever switch to using tape again, I'll have to do a run-off between Supertape and ST-30.
