I got tired of being in the water all day and drinking hot pop so I built in an acrylic tank so I can have a cold drink. It is approx 12 x15x12 I sealed and glued it to gether with crazy glue and siliconed the joints. the question I have is fristly do you think crazy glue and silicone will hold the joints full with Ice. and should I reenforce the acrylic with plywood and foam as it sits in my boat. I ll try and post a pic later but thoughts. The acrylic is 1/4 inch thick
