I want to make the plywood and epoxy paint type trays that are shown here:  http://www.fatalii.net/urban/u3-4.jpg and here http://fatalii.net/growing/index.php?option=com_content&task=view&id=86&Itemid=100


I was wondering about epoxy paint as I have never worked with it.  Do you know where to find this type of paint and do you have a particular brand/part number of paint that is recommended?  I looked into marine bottom paint but it seems to run about $150/gallon.

Thank you!
