I found a site ( http://www.jgreer.com/Foam Page.htm ) that has the following;<br />AeroMarine 2# Density Foam Gallon Kit; Consists of 1 gallon of Part A and 1 gallon of Part B.<br />Yields 8 cubic feet. <br />The cost for this 2 gallon set is $68. I've not found this anywhere else for this low of a cost. Has anyone used their foam before and is this what I would want to use in my rebuild? I was debating on using block foam due to cost but this sounds to good to pass up.
