Skullz Posted September 13, 2010 Report Share Posted September 13, 2010 If i'm not mistaken most liquid sound deadener are too thick to be sprayed on and have to be brushed but not 100% positive on that. Yes it will add mass to your car whatever you use. Quote 01 Ford focus ZX3 Pioneer AVH-X491BHS PPI PC 4800.2 Morel Maximo 6.5" x2 Link to comment Share on other sites More sharing options...
zachfowler222 Posted September 13, 2010 Author Report Share Posted September 13, 2010 so like if i was to use line x bed liner it would work? Quote I SCAM PEOPLE OUT OF MONEY... AVOID ME LIKE I AM AN AIDS INFECTED RETARD... Link to comment Share on other sites More sharing options...
Skullz Posted September 13, 2010 Report Share Posted September 13, 2010 Wouldn't work very well as it would dry rock hard and thats not what your wanting to have happen, it works a lot better if it stays like a rubber consistency to dampen the sound waves.

raytard Posted September 13, 2010 Report Share Posted September 13, 2010 most dampeners even say that they are a "mass added dampener" when you add mass to ANYTHING it lowers the resonant frequency. the objective in a car is to lower the frequency of a "rattle" to a "flex", in layman terms you're making it heavy enough that it resonates so low you can't hear it anymore problem is, you cant feasibly make a car stop resonating completely (well you can, check out alma gate's bronco as an example. not all of us can dump hundreds of pounds of concrete into our cars, but she did and it worked great) so what all us normal people do is something "good enough" the thing about the stuff you see on the market, like damplifier and dynamat, is that they use butyl to stick and conform and add mass, and an aluminum layer that also adds mass as well as a bit of ridgidity(and keeps all that sticky stuff where it should be) you can use bedliner, but make sure it stays elastic when it dries, if it doesn't there is a good chance it will chip off because the panels will still resonate.

How would you make sure that it stays elastic?

zachfowler222 Posted September 13, 2010 Author Report Share Posted September 13, 2010 How would you make sure that it stays elastic? im wondering the same so any help/advice would be good Quote I SCAM PEOPLE OUT OF MONEY...

siccostyle Posted September 13, 2010 Report Share Posted September 13, 2010 Maybe an additive mixed in before you spray it?

raytard Posted September 14, 2010 Report Share Posted September 14, 2010 try a couple brands and see which one can be bent and not crack, spray it on tinfoil or something and bend it when it dries, if you can bend it way back and forth without cracking or peeling off it should be fine Quote Build: http://www.stevemeadedesigns.com/board/ind...hl=avalon+build monster/rockford/kicker/stinger cables, pioneer source, jbl highs/amps, kinetik/shuriken batts, iraggi alt, dei security, dc subs(atleast for now) Team DC Link to comment Share on other sites More sharing options...
CHEMMINS Posted September 14, 2010 Report Share Posted September 14, 2010 Are y'all on crack..... Just use the liner straight up. It doesn't matter if it goes hard. It is not going to crack on moving panels. I bet none of you run trucks with a real bedliner in it? We throw heave ass shit in out trucks, heavy enough to dent the floor of the box, drag stuff out of the box, and 90% of liners hold up no questions asked. So if you think a little vibration from your system is going to make it flake off.....think again. Quote Link to comment Share on other sites More sharing options...
