Generator quieting
I have a Honda 3000 EM, I am looking for some ideas to quiet it down. Anyone had success with this, want to share some ideas?

As far as I can tell, the most cost-effective sound deadening material is called Homasote -- it is sold under a variety of names. Essentially, it comes in half inch thick sheets, 4 feet by 8 feet, and it is compressed cellulose.
Maybe there is a cost-effective way to waterproof the cellulose sheeting? And to use something else for the exhaust baffle.
I first tried a sheet product that sounds much like Homasote but it didn't work at all as it was way too heavy and crumbled easily. Any quiet box I've looked at online that's demonstrated excellent results has always used dense noise control barrier foam such as that product I link to earlier from West Marine. I have to admit I'm SO tempted to try it myself, except my wife would kill me if she knew I spent that much to buy a sheet of it. :E. As I mentioned earlier jauguston gifted me a piece of high temperature batting that I used for the exhaust box but had that not been available to me I think I'd have used Roxul stone wool, the only problem being I'd have had to pay for a whole bag of it when all I needed was a small piece.
