Just one more tip....NEVER, and I mean NEVER use the lip of the top of the tube that holds the cap to tap UP on. NEVER. If you didn't hear that, I'll say it again...NEVER!!!!
That piece is just pressed on the top of the tube. Guess what happens when you try to tap up on it? ....a long time ago when I had peach fuzz for a mustache, I learned this the hard way. Don't be that young and dumb me. Come to think of it, don't be that old and dumb me now, either. I don't have a choice, though.
