Re: should I produce a 60 mil Second Skin vibration damper?
I vote no.
You've got damplifier, and then you've got STFU-80. If a person needed something in-between, they could always go for double layers of damplifier, hence the need to buy more.
Actually, I find it's much easier to have double layers with that dimple, rather than the smooth ones I bought over here in Korea.
