i recommend this stuff! i have 2 basses that #1-picked up an AM radio talk show,lol. #2-bass when i moved or turned made loud cracking sounds. i purchased the sheilding paint(stewmac).after disassembling everything i applied 3 coats,letting each coat dry completely.i even removed the foil backing on the cavity cover and applied 3 coats to that. all i can say is now both basses have zero noise! great product!
