Damn, I need to get some of this stuff. So it's styrofoam first which is a spray on foam (never used it, heard the name, don't know what it's used for or hat it looks like). What other applications is it used for? Maybe I can explain myself to the hardware shop better if I give them a more common usage.
And then a fiberglass epoxy resin over the top?
