i have no idea how much wax i've used this year. maybe i'll count it up later.

my board just sucks that wax up.

if your iron is scratchin on your board you could put a little more wax on it, you should have a nice smooth coat on it and your iron not hit your base. no one can tell you exactly how long your stick of wax should last, the only certain thing is it will last until it is gone.  the more you wax it the harder and faster your base will be and the less scratches it will get.

I'm working with bluebird all temp wax, and I probably use about 1 cubic inch of wax or less everytime I wax.
