Mark,
I notice you say "should be about the same" so you must have missed
my point. Dynamat and roofing stuff is exactly the same - so "should
be about the same" should read "are exactly the same". Sorry to be
so picky but I hate to see people being ripped off. $11 per sqft
instead of $1.30 is just too much !! My floor in the MGB is one
piece including up the sides. So I have a beautiful clean shiny
aluminium seamless finish that will hold water up to inches deep!!
