After what must be close to 20 years, my Fein Turbo II sound deadening insulation inside the top housing has deteriorated to the point of being ineffective as a sound absorbing barrier and crumbles if touched... I can get to it easy enough, and it would appear that i'd need 2 thicknesses (roughly 1/2" and 1" thick) of sound deadening foam insulation to replace/repair. Has anybody ever done this and found a good place to get this insulation in small quantities? I would only need a few square feet at most. A link to a source would be much appreciated
Thanks!
