Yes! It is totally okay to use the BFST or the ColdCure over the area where you have applied KB Tape.
The tape is designed to last 1-3 days per application. If the warmth from the BFST causes the adhesive to become a little too sticky, you can apply an oil based product such as coconut oil or vaseline around the edges of the tape, and take it off in the shower with hot water to make removal easier.
