Just wondering if anyone has an opinion/experience using any kind of sound damping material in a fiberglass car?

have you done a searched in any of the post?

I know theres a few on damping, not sure about in a fiberglass car though

If we learn from each success and

each failure, then we can improve ourselves

Yea you should just be able to use some dynamat or some tsuinami deading on that.

Maybe you should research this alittle more before making an investment in sound damping material as it can be relatively expensive. Check with your car manufacturer and try to find out what they might have used in your car or what they recommend. Much luck with that ... some alternatives to Dynamat check out--fatmat or brown bread, maybe even some discount foams etc from Homedepot...to save money.. just in case

If you go cheap on the damping then you might as well go cheap on all of the componets as well. Sound damping is just as important. Why havea nice system if your trunk rattles and everything in your car rattle to the beat of the bass?

In some cases it makes more difference in fiberglass. Although dynamat type systems are designed for glueing to sheet metal and to convert vibration into heat, they will also work on fiberglass. However, most vibration from fiberglass is due to resonances in the material itself as opposed to rattles from welds or bolts or unsupported sections like in sheet metal. In many cases, good old spun mat or foam rubber sound deadener - or even carpet - can work wonders on fiberglass panels that are vibrating. Adding mass to them will change their sympathetic resonance frequency to something below audible.

It definatly makes a difference on fiberglass cars. I did the entire interior of a 74 stingray and it made a big difference. With that being said I found that Brownbread actually worked better in regards to sticking to the body than the dynamat did because we tried both. I do think that dynamat is the superior brand but Brown Bread made a huge difference and it probally comes down the fact that you wont notice a difference because you will never know what dynamat would have done for you so the brown bread will be more than sufficient. What kind of car is this anyways
