Im getting ready to do some more sound dampening to my vehicle and need some clarification.
We will use dynamat extreme as our example for the questions.
1. Can I put 2 layers on roof and 2 layers on headliner also? My understanding is yes because it states in the rules..."at a given point"
· The OEM headliner (or an equivalent replacement) must remain in place for those areas in front of the B-Pillar.
· The OEM door panels (or an equivalent replacement) must remain in place for those areas in front of the B-Pillar.
· The OEM carpeting (or an equivalent replacement) must remain in place for those areas in front of the B-Pillar.
· Sound damping materials may be used to reduce vibration when installed in accordance with the manufacturer’s recommended installation instructions. The maximum total thickness of sound damping material applied at a given point may not exceed 5/32 inch (4mm). The sound damping application may consist of mat-type material, spray-on material, or a combination of the two. A maximum of 2 layers of mat-type material may be used in any application, even if the total thickness of the sound damping material(s) is less than 5/32 inch (4mm).
· Expanding foam may be used sparingly in front of the B-Pillar to seal small openings or reduce vibration, but may not be used to fill voids or other large cavities (such as the dashboard or doors).

This a question that has been asked since the start of the year, it needs addressing and it needs to be done before the finals.
What exactly is a given point?
Wouldnt it be better to have a list of points you "can" deaden rather than people deadening everything and saying its a "given point".

This question has been addressed several times this year.
I agree, listing points would be great. Having no limit at all would be better.

So what is your answer Steve? Looking for a yes or no to can I dampen the headliner or not.

David, save yourself the time and hassle and call Wayne. From my understanding, there have been several conflicting opinions by head judges as to what is the acceptable way to apply the sound dampening. Earlier this year, there was an open debate between Steve and Tor as to how they felt the dampener could be applied. I think that it was nearly agreed across the board that different portions of the vehicle have 2 SEPERATE surfaces that may be double layered in the same area. Example of this would be your door. If you remove your door panel you can reach behind the initial metal framing and apply mat to the outside skin. This surface may have 2 layers. Then you may apply a double layer to the metal door frame, and then mount the door panel back onto that. My opinion is that you MAY NOT apply mat to the headliner. You may however apply a double layer of mat to the vehicles' skin under the headliner. BUT, I am not a judge, just trying to apply what I've read and understood from recent posts.

I like the Idea that Spkrman has.. maybe we can change that rule to read that like no 2 surfaces within 1.5" if each other can have the 2 layer?? or something of that effect later Doug
