This is the stuff used for sound deadening on car panels and the like. My friend has a garage and uses Dynamat. It is expensive.
I am looking at the weight aspects and also it is fairly easy to squirt this sort of stuff http://www.screwfix.com/p/no-nonsens...ld-750ml/45865 into a box section.
When I get to it, it wouldn't hurt to fill the gantry and frame, especially if you put in plastic tubes to run wiring. I am really looking to find out if anyone has already tried it.
If anyone is interested PM me your e-mail address and i will send you the Doc i was looking @ I tried over on the 3M site but couldn't find the stuff used in the article. it was 3M Scotchdamp ISD-112 and it was 1mm thick.
I remember that i've seen something interesting one year ago... about filling a milling machine with an epoxy concrete...
