Mike H. Posted August 16, 2006 Report Share Posted August 16, 2006 Folks,Just wanted your take on what to use to dampen door panels. I developed a rattle that I can't pinpoint ever since I took of both my front panels for something. What do you recommend? Should I get some foam to cover the door panels? Anyone have pictures of their dampened door panels? Thanks! Link to comment Share on other sites More sharing options...
prasamin Posted August 16, 2006 Report Share Posted August 16, 2006 I have peel and seal in all my panels....helped REDUCE rattles...i need to add another layer to dampen more.I know a place to get that stuff, just holler if you want to try it.

Geevs Posted August 16, 2006 Report Share Posted August 16, 2006 Couldn't find "Peel N Seal" up here. Only found "Jiffy Seal" at local Home Depot. It's a 6" x 30' roll of rubber/asphalt tape that has self-adhesive on one side but does NOT have aluminum layer on the other. Label says it's 40mil thick and "contains materials known to cause cancer in State of CA". Is this more or less the same stuff as Peel N Seal?Mike, didn't you use Spectrum sound dampening paint on your car? If so, how's it work out for you?

TM850R Posted August 16, 2006 Report Share Posted August 16, 2006 Sounds like its more or less the same thing as Dynamat and Peel and Seel. Just without the shiney cover.It would be best to use spray on dampering in the trunk. The doors would seem a bit complicated to mask off. Link to comment Share on other sites More sharing options...
Owned Posted August 17, 2006 Report Share Posted August 17, 2006 Peel n seal and Jiffy Seal are the same thing, for our purposes, anyways. It's just asphalt with latex mixed in. The aluminum is there to provide both a backing and a way to deal with temperature changes. I would not advise someone to use this in their vehicle and never have. Products like Fatmat, eDead, Brownbread, NORMAL Dynamat, etc, are all basically the same as a Peel n Seal/Jiffy Seal roofing product. It's all just asphalt and latex. The reason you see Peel N Seal and other such products decline in deadening ability (and also fall/peel off of surfaces) is because asphalt not only melts with heat but also becomes brittle with cold. It doesn't take much to see these results, either, especially in a vehicle that's parked in the sun with the windows up or left outside during the winter. What makes it worse, is even though it's possible for a roof to see the same temperatures, a roof does not have bad roads and a sound system rattling the daylights out of it.If you want something of quality, you need something butyl based with added asphalt (different than asphalt based), or butyl with a non-asphalt filler. Products like these are much better at everything than roofing products are and most importantly are designed to be in a vehicle. They also do not give off a stink like an asphalt mat will. However, they do cost more. Butyl based products would be something like Damplifier Pro, Dynamat Xtreme, Hushmat Ultra, RAAMat BXT, B-Quiet Ultimate, ect. There IS a difference.You are also not confined to mats, there are other options, however, mats are generally easier to use. There are foam mats available, but they are generally pricey once you get into the thicker mats. Now that we have that out of the way, if you are able to figure out what is causing the noise and want to avoid actually sound dampening your doors, you could get away with a piece of nappy side Velcro stuck to one of the two surfaces that are rubbing against eachother. This would be the cheapest and easiest solution. I think most cars could do with a little noise reduction, though. Link to comment Share on other sites More sharing options...

Owned Posted August 17, 2006 Report Share Posted August 17, 2006 Sprays work well but can get messy and arn't always the easiest to work with. There are many good sprays out on the market right now, though.Cascade, who makes a very nice mat, btw, has some nice liquid and paste products. They're also a sponsor of the Volvo Speed S60 . They make a product for using between glass layers while you're building an enclosure that I've been itching to try, too. Link to comment Share on other sites More sharing options...
Mike H. Posted August 17, 2006 Author Report Share Posted August 17, 2006 Mike, didn't you use Spectrum sound dampening paint on your car? If so, how's it work out for you?I did, never got around to finishing the project. But for the time I've used it, really easy to use but I don't think I ever got the full benefit because I didn't finish the project. Link to comment Share on other sites More sharing options...

It didn't help much to get rid of the rattle and clunking noise - which has led me to believe it's not coming from the tailgate but the entire rear suspension area.I still undecided whether to apply spectrum to the floor of the wagon area, or use Peel-N-Seal type.

I prefer the grey look over the shiny metal. I never got around to finishing dampening the floor of the wagon (did the sides with liquid only, pain in the butt to get mat in there) so never put the spectrum on. It's on my short list for August/September before it gets too cold. Link to comment Share on other sites More sharing options...
cRRRRazy Posted August 17, 2006 Report Share Posted August 17, 2006 if its a rattle i would replace the plastic clips that hold the panels in before messing with anything else Link to comment Share on other sites More sharing options...
