How Bulletproof Is Flex Tape?

If you can tape a boat back together, why can't you layer up for a little added protection? We know from extensive redneck science that if you have enough duct tape, you can stop a small margin of very small arms... Paper is much more effective, yes, but we're talking about tape.

Don't get your hopes up.

Also, don't be the idiot that tries 'real world testing' of any of this. Punching holes in tape is fine, but risking a GSW is just plain stupid. I'm almost ashamed that I have to say that. Literally, I have to say that.
