I'm doing a major refit of my Morgan-462.

While I'm re-paining the walls and bilge in the engine room to get the new engine and genset into the boat, I have not given soundproofing much thought.

I know that almost everyone will have an opinion on what to use or what is best, but my question is: does anyone know of a comparison site where different soundproofing products are compared and rated?

I did see a "paint on" product which worked great on metal but was less effective on wood and fiberglass. That's why I'm looking for a site which may compare the top selling items and show how they rate, differ and how much they cost.
