Hey guys, I was thinking with my next ride i would go out and completely deaden the entire car. But i'm wondering if this is really worth it or should i just stick to doing my main floor area's, tire wells, firewall and the boot? Oh yes doors too of course.

Up for any suggestions on what you guys think is best.
Aim of this is basically want to decrease my road noise throughout the car. More for a comfort thing to start with than stereo. posted_image

depends on the car you buy.... buy an older European car and you'll be amazed at the sound dampening they put in years back ( any who has tried to drill a pass hole thru the firewall of an old BMW, Benz, Saab, etc will know exactly what i'm talking about )

There isn't too many area's on the list you have not mentioned.

It comes down to how you will do it, and with what products / methods which will ultimately reflect what you reap in terms of sound deadening.

The most basic step in this is having the entire undercarriage coated with a rubberized coating with the appropiate thickness.

Do not use those products which are asphalt based, the reason being is that the material always remains semi-wet and allows road debris to impact, and stick to the coating.

Using under coating which is used for bed liners such as Rhino lining is not to be used on the under carriage as well. The reason being is that the material is very tough and is *when* dried is very hard, and the road noise will simply make thumping noises instead of rattles.

Remember, applying the undercoating to only plastic wheel well splash guards is only half the job. The inner fender must also be done to reap the ultimate results.

Using applying the same material in the interior is also fine, if you know for a fact those area's are free of existing rust, or area's not requiring maintenance.

Once the area is coated you may apply simple rubber under carpeting to any inner panels.

Applying the above methods not only work, but utilizes alot less money compared to using Dynamat, Brown Bread, or any similar sound deadening products.

Those on a tight budget will reap the most benefit going this route.
