hey all..having problems with mr frost. my cell has plates seperated with neoproplene(no spell check please) compressed between 2 plastic plates by bolting all together. with a very cold spell here in sunny ireland my water is freezing and swelling pushing out my spacers until i get a leak. now i've heard ethanol is a good anti-freeze but its very expensive here,£52 for a small bottle, anyone got any bright ideas as its not getting any warmer?
