Spray or brush on material for inside sheet metal?


I just purchased a very nice early 90's 4/dac Technics CDP (SLP-50S) which sounds very nice but I would like to add a damping substance to the inside of the very thin sheet metal cover. Is there something out there which will adhere to the metal (add weight/isolation) and possibly improve the sonics? I've never even thought of doing this to other cdp's, but this one has so much potential for improvement I'd thought I'd ask for your opinions. (BTW, changed the stock ac chord (20-24ga.)w/
a Radio Shack 18ga. ac chord ($2.99) and the difference was noticeable.) Thanks, Bill

Music Direct offers a product manufactored by 3M. It is a constraint layer damping sheet, that is made up of a 10 mil stainless steel sheet, backed with an exclusive 5 mil proprietry 3M viscoelastic damping compound.

This damping compound dissapates vibrations by a sheering action (claimed to be superior in effect) rather than converting the vibration to heat as most elastomers do.

The 10 mil stainless steel sheets will increase the rigidity of the the CD top cover and will reduce the mechanical resonance that can impede the performance of your equipment.

I looked at the Music Direct on line catalog, but it wasn't listed, so you may have to call them. 800-449-8333. It is listed in thier Mail order catalog, 4" by 6" sheet runs $9.99 plus shipping.
