Toying with the idea of trying to get a TNT Audio "Flexyrack" together. I'm interested in this "damping paint" that the TNT site recommends using to reduce vibration in the shelves. Does this really do anything, or is it just snake oil? So far I've come across two varieties on the 'Net - "Noise Killer Yellow" from Rockford Fosgate, and Brax "eXvibrations". Would anyone recommend either over the other, or does anyone have another brand that they favour?
