hmm... LBV very uncomfy lah.
anyway.. the best way to get rid of black tape sticky stuff is not
to use electrical insulating tape.
what i used is hockey tape... the ones use to tape hockey sticks
for better grip and splinter prevention.
its quite hard to get.. but one place i know is Skateline.
it's clean. Matt and cloth type, "matches" the fabric of your
sbo.
and your sbo will be unique since your platoon mates are using
insulating tape.
