casey, as mentioned above, I drilled a 1/4" hole in the center of the lid and poured out small amounts each time, wiped it clean and put a new piece of duct tape over it each time. Its been hot as a firecracker here and I"ve used some out the can every few days and its still good.
I had the hookey puck thing happen to me to.....then another bolter, I forgot his name,mentioned drilling a hole in the lid and it works for me.
Anwyone else tried this?.... am I just lucky this go round?
