Has anybody used the sound deadener DBkill vs dynamat?
Want to do the van any other suggestions,

RaamAudio BXT is a good substitute for Dynamat. Similar mass with an alu backing. It is more flexible which can be a problem when trying to get behind the inner skins on doors. It is great when rolling it to conform to panel lines... I ordered it direct from the US and it is much cheaper than Dynamat.

There are other generic products...

if you are looking at cutting out noise etc have a look at my two recent conversions I am a motor trimmer by trade so I use a blended wool composite soundeadner it can be easily glued to all outer surfaces etc except the front doors as they are wet so glue to back of trim itself . The stuff is 2 metres wide and can be purchased by the metre This my mate's van done late last year My weekend project on my mates T5, MADE IT QUIET . And this our new van done recently New T5 Project

Anyone know anything about bd-kill? Though I'd post here instead of making a new thread.

No offence but if you are to comprehensively sound proof a T5 that is the roof and sides and tailgate side door and front doors and floor you will need around 10 to 12 packs to do the job properly that's around $1000 Plus if you have a look at both the conversions I have done the material that I use is 1/3 rd of the price and trust me I can tell you it does work . I would admit here that as I am a motor trimmer by trade I have the spray glue etc needed to do the job . I have converted dozens of different vans over the years and no complaints , I have seen some of this type of stuff DB Kill and Dyna Mat fall off some surfaces . Its a personal choice but I thought it worth mentioning .

While not knowing the direct answer, I am thinking:

I suppose dbkill (or similar product) and wool work in different ways: dbkill sticks to metal panels to stop them from vibrating by weighing them down, thus preventing noise from being generated in the first place. In contrast, wool works by blocking out the original amount of noise.

With wool it seems more important to cover the entire area to prevent noise going thru gaps in the wool. With dbkill, it is enough to stick a patch in the middle of a panel to dampen it.

So, if the noise is generated externally (e.g by tyres) then something covering entire area is needed e.g. wool. If the noise is generated by vibrating panels, then dbkill patches will do. Use both for best results.

I'm looking to use it in my golf! Just thought I wouldn't start a whole new thread when there was one basically the same just in a different section.

Ah now I see that if you have a sedan hatchback that will throw a different tilt on the problem . Now with a van 90% of the surface is internal with no water problem when we use the wool blend we cut over size so that we can tuck it right up to the edges of the internal body parts any off cuts are also used to fill pillars etc .If you are doing a sedan type body there are only a few areas that can be done . like the rear hatch and sides etc. Doors will be a problem as VW use a separate internal panel to hold power windows & speakers to the inner part so applying any sound proof will be difficult I actually glued the wool to the back of the door trim itself see photo in my post .The DB kill will work better from a thickness point of view under the carpets . The wool blend because of its thickness will probably cause the carpet to no longer sit neatly . Some sheets of DBkill stuck to the very outer skin of each door will help with sound and vibrations as it may not retain water running down the inner door skin . I would not attempt to do the roof skin as removal of the internal hardware will cause you to slit your wrists with frustration . Most Golfs built in the last ten years were clearly designed by idiots who seem to think people will never remove them , I now refuse to fit a sunroof to the current Golf 7 as it can take 1.5 hours just to remove the handles and sunvisors etc then you have to try and refit them good luck ! So as Tig-uan states the best result would be a combination of both , I have preference with the wool as I can cover every surface when doing vans easily . IMO
