Here is a link to sound dampening panels. The post is really for the video that you can watch on the website. They test the products on 2 1970s type 2s. Just an interesting video. i realize the old school guys here love the hearing loss, rattled balls and uncomfortable ride. It's part of the experience........ So, this is just an FYI for interest sake...... www.dynamat.com |

Not that I doubt the effectiveness of the Dynamat but ….. Why did they not do a comparison test of before and after Dynamating the Panel? It is hardly a fair comparison of a Panel vs. Camper. They never showed the inside of each vehicle…Was it a bare Panel, or does it have some interior(looks kind of like it might when Pete was driving it)? I mean who would drive a bare Panel without ear muffs?  I am sure Brent's Old Blue has quietened somewhat since he put the interior in. As an old(school) guy I can say that the possibility of future hearing loss scares me. My dad after driving from call to call over great distances in a bare van or suburban full of Xerox parts could have really benefitted from this stuff. Of course Xerox wouldn't even let him have an air conditioner in the south Okanagan, so I don't think if Dynamat had been around then that they would have sprung for it.  Another thing…Pete needs to bone up on his years…the Panel is a 71  Here is a direct link to Youtube if Dynamat decides to replace the video on their site: |

Although I am certain that Dynamat does a fine job, it is eye wateringly expensive, particularly in something the size of a VW bus which has lots of surface area. Last time I checked these guys were considerably cheaper for an ostensibly similar product. www.b-quiet.comIt would be interesting to hear other member's experiences with sound deadening products, particularly as this is on my imminent to do list (and has been for some time?  ). I am seriously considering some of the household roof flashing materials which appear to be similar to some of the commercially available purpose made materials. |

My Dad and his hot rod buddies have all used sound deadening material in their projects. Not one of them has used Dynamat, however due to the "extreme" cost. I have never priced the stuff out, but I have heard from many different people it is just too expensive...

I used the stuff from Rona, wcp recommended on his bespoke posts.
Nice easy stuff to work with, but was warned that with hot and cold temps, the sticky might not stand up, and should use a bonding material. I didn't and I did see one spot let loose a bit during its exposure before covering with insulation and panels .
I did notice it was quieter once applied, but the interior definitely adds a Tonnes more quieting material, lol.
Still freak ing loud when your pushing 1600 cc' of pure vw power, lol. Dam empi exhaust, lol

Where did you get your Dynamat from Frank? Did you cover all over the inside of the car, or just stick on "tiles" to those panels where you would expect vibration?

Since my bus is stripped down to the metal, I have decided to go with lizard skin. It is a 2 step process and is applied by spray gun. The first product is sound control, spray it on about 1 mm thick all over the inside, headliner and floor. It also has rust prevention as it is a a great layer over the primer. The second product is the ceramic insulator which prevents heat from entering. It is also about 1 mm thick. The lizard skin is big with the mustang, corvette and classic car crowd. There are some really cool videos on YouTube you should check out or do a samba search for pictures. You can also put these products on the inside of the pop top to keep it cool and take away any unwanted noise. Not sure if that is worth it as fibreglass is already deadened quite a bit, but you have the option. It can be painted as well. This stuff ain't cheap and not easy to find in Canada. The Old Car shop in Langley had it, so I bought 2 gallons of each application plus the spray gun kit delivered for $528. Ouch yes !.. Keep in mind, it quiets the bus, insulates it and provides a rust barrier. I will still add some nasa foil insulation to fill out cavities where necessary.
If I wasn't doing a full restoration and the bus wasn't gutted, I would use Dynamat. You only need to apply the mats to 25% of the surface you intend to dampen. Eventhough a little pricey, 36 sq ft box for $250 delivered off amazon Canada would go along way.
I will send pictures once I get at it in a month or two.
