Sound proofing


Recommended Posts

I used Dynamat Extreme from under the back seat to the rear of the car. took me 5 hrs start to finish and worth the effort!

Thanks for the reply, I was looking into the stuff you used then the liquid sound proofing looked promising you can brush on or spray on. You can spray your undercarriage and its water based sealant for easy clean up and you done in half the time. Also less the weight of the sheets. Sorry can't remember the site due dead brain cells.

Has anyone sound proof their shelby yet???? Been looking into it for sound quality (stereo, road noise). From what, I have been reading the liquid application is the easy and fastest way.

I don't know much about liquid sound proofing, but if it's water soluble for easy clean-up, it is not impervious to moisture. Thus, using it on the undercarriage of a car may lead to deterioration of the sound proofing material over time, and possiblu create hidden rust issues as well. In my past, I have discovered some shortcomings with undercoating and "Ziebart" like products. But, like I said, I have not had any recent experience in this area.

 

I have used Dynamat extensively, and I find it easy (though time-consuming) to work with. I've used it in doors and under the carpeting to quiet a passenger cabin, but not on my SGT...Yet. Moreover, I have learned that Dynamat also has a "heat transfer barrier" quality to it.

 

I don't know about y'all, but LuLu's floor pan/firewall area under the dash gets quite warm at times. Dynamat will reduce this.

 

Also, apply some caution when working under the rear seat cushion. Access to the SGT's dual fuel pumps are located there. Be careful in cutting and triming, and don't glue anything down. Just tack it in place at corners and along seams with some 3M tape, velcro, or, silicone. It may have to get taken up someday, and Dynamat is not cheap.

 

Another issue is the sound itself. Overuse sound proofing and you may not detect a serious problem (such as detonation) until it's too late. Use sound proofing sparingly, some things need to be heard as an early warning system.

 

Last but not least, glass is not good at insulating sound from outside the passenger cabin. You can pack the doors and mat the floor pan and trunk areas, but you will always have sound (vibration) penetrating the passenger cabin through glass. Dynamat may be disappointing once considering the cost, and the end benefit.

 

Happy motoring, gents.

From what, I have been reading the liquid will dry solid and air tight and is used for rust preventive (if I spelled that right) will notbreak apart or retain water. They tell you that you can spray the whole trunk and anywhere in car. But also undercarriage, I might use both spray the inside of door and what, I mean by that is the door shell not under door panel figure that would work best. But, I have been wrong before and take it from there. Spraying underneath would cause problems if you get it on the bolts or hangers. And going to doc's pray he decreases my meds so my brain starts working again. I don't think the wife and baby can handle me leaving them at my mothers and driving home without them after my board hearing. 1hr 45 each way or forgeting your walking down the steps should watch me with a chain saw my wife won't. :banghead::confused:
