Dynamat 11103 is a great product and works quite well even though I'm not using it for it's intended purpose. i've installed Dynamat in the cockpit floor area of an all aluminum experimental aircraft to reduce vibration and provide some insulation from cold in the winter. The product is working well with the exception of wear. I don't believe it was intended to wear and as such I've had to add .032 aluninmu skid plates to protect it from the heels of the pilot and co-pilot's shoes. When working the rudders pedals Dynamat was beginning to tear. That solution has solved the wear problem, now if i could just dress up the surface a bit it would be great.
