What kind of noise? Have you thought of spraying foam insulation and then undercoating it?

road noise. mostly the tires i think. thought of foam but can't find any that would work. the spray cans don't seem to work like they used to. any ideas?
thanks, dave

I had a noise in my 05 Dolphin and it turn out to be the grill vibrating and touching the fiber glass. It sounded like it was coming from the wheel well on the passenger side. It only happened at surten speeds and varied if I was going into the wind or with the wind. A bungy cord rapped around the grill stoped the niose and late I put rubber isolators in the mounts.

I am doing a lot of soundproofing in my coach right now. There are plenty of automotive type products like Dynamat and Second Skin Audio's Damplifier. They are pretty expensive, and they basically are a buytl rubber and tinfoil. They dampen the metal's resonance.

I found an almost identical product at Menards in the form of a 6" wide roll of what looks like a product you use to seal a leaky gutter. It's a 6" by 25' roll I bought for $12.

It would sell under names like Peel & Seal or something like that. It is found in the roofing department usually and make SURE you don't buy one that is asphalt based, as they don't stick nearly as well as the butyl rubber.

I have lined my door, behind the TV, the floor underneath the coach (over the tires) and the firewall with it. I can already tell a large difference.

Good luck!

I used a grease and wax remover... to have a nice clean surface and it sticks real well.

great idea, I have a roll of that sticky stuff, never thought about the RV

Don't think we have a menards around here. What name should i look for? Thanks again, dave

Home Depot, Lowes, Fleet Farm, ect...

It's a roofing/gutter product... again - make sure you find one that is a butyl rubber based, not asphalt based.

Also - it needs to be thick. Typically somewhere in the 30-50mils range. The super thin stuff won't do enough unless you put several layers on and then you lose in the cost effectiveness department.

Or just buy the "real" stuff.. Dynamat or Second Skin "Damplifier"
