Originally posted by ramos I put a layer or two of the deadening material on the sheet metal itself. Then fill in the empty spaces behind the plastic trim panels with regular old houshold insulation. Works like a charm. The sound deadener kills the panel resonations and the insulation kills road noise. If you have plastic panels buzzing I would suggest weather stripping foam like they sell at wally world or lowes. Put it on the back of the plastic panels where they contact the metal. And your buzzing panels will no longer buzz. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

theres a poor mans dynomat sorta its at your local builders warehouse lowes,homedepot ect.it is a roofing material with a metalic side and a sticky side it is used for roof repairs around flashing areas but it has the same qualities as dynomat desperate give it a try.

your sound pressure can blow isulation particles all over your vehicle it could be quite a mess. i would recomend a non fiberglass insulation its like a rats nest insulation hood liner insulation or an old comforter not in use.

Doesn't rattling depend on the amount of bass.

I didn't say put it in your enclosure. If you put it behind trim panels how is the sound pressure going to blow it all over the place ?

The only problem with the ice gaurd material is when the heat gets to it. It's meant for flat surfaces that are horizontal. If your area get's real hot in the summer time I wouldn't suggest it. It will slide down and create a mess. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

There are other reasons to sound deaden a car. not just rattling. Sound deadening also blocks out road noise. Which lowers the noise floor inside the car. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

your trim still vibrates doesnt it you just cant here it and if it vibrates then particles of fiberglass are shook up but if you can get it secured go for it . it may not be a problem just a thought.

The way i understand it is anything that touches both your interior panels and your exterior walls will create a more solid wall all together that shouldnt resonate. In my case im not so much worried about sound deadening beacause i think that will be taken care of with 2 layers of dynamat and a layer of spray on dynamat..i just want everything to be solid and not rattle. Im thinkin doing something as simple as stuffing foam between the body panels or like stuffing pillows back there will work... just my thinking after reading all of this.

wise choice the fiberglasss is to much of a mess even on the install . trust me ive put up alot of insulation for a living i understood it was for rattles. but theres a much cleaner and effective way with out the itch.

ps a wise man once said you can catch more flies with honey than viniger but then again who want more flies.
