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!!
