where to find 3M Damping sheets?


Anyone know of a source of 3M's constrained-layer damping sheets?

Thanks.

Thanks, Tvad. Actually I just found them at Music Direct although I couldn't find them on my first search. I'll try MPA in the future to compare prices.
You can buy an excellent assortment of noise and vibration damping sheets from smallparts.com. Just type "damping sheet" into the search parameter. I've had good results with their products.
