Sound Deadening

[rfsee]

if you cover the floor of a vehicle with dynamat does it have to be covered with a rigid material to prevent damage to the dynamat?

At our shop we use Rhino Liner on the inside of the trunk lid, and inside the doors and the spair tire well it stops all vibration can be color matched, and looks better that foil looking dynomat.

Any shop that does spary in bedliners will be able to do the trunk for you i would take it off take it to them with everything masked that you do not want to get sprayed. it will not ratle anymore.

actually, if it is applied correctly - it looks pretty good

So this rhino liner stuff is like a sheet material aswell but it can be color matched?

My other option is to sound deaden the trunk and then take it off and have it painted by a shop?

[PaulD]

no, the bedliner stuff is like a harder version of dynomat. It sprays on

[scarlemthug]

:OThanx

So this stuff could be color matched to my car and just sprayed on and work as well as dynamat?

[PaulD]

I have no experience with the stuff, so I will have to take cfmotorsports word on how well it works as a sound deadener.

What about using an undercarriage spray?


There is a product from dupli-color that is for undercarriage spraying and it eliminates sound and rust? Do you think this would be a good option for my trunk?

I have brown bread on my trunk lid and around most of my trunk. The stuff is just silver and when most people see my trunk they say hey cool you have dynamat. Im like no but thanks for noticing. it looks just fine but if you need to paint it you can. I just dont think it looks that bad.

Oh and as far as weight goes i think putting brown bread in my trunk added about 1lb to the my car. DAMN IT SLOWWWED ME DOWN

[gnushit]

i saw brown bread in ebay and it seemed like a good price, does it work as well as dynamat xtreme in durability (lifespan), and reducing road noise?

[SPLThunder]

Oh yeah. I think it works just as good if not better. My thousand watts RMS dont make nearly the amount of rattle that they did before. I spent over 100$ for the 35 square ft and i dont regret it.

[gnushit]

thanks for the info spl. that stuff has to weigh more than a pound, it's more like 10-20 pounds, you know it'll take 30 more horses to make it up!

[SPLThunder]

Ok so it add a few pounds but compared to my box and subs that weigh more like 100-150lbs it didnt really matter to much for me. If you are a real freak over needing your car to be that light then i wonder why you would put a system in it at all.
simply put the mass ratio of sounddeadening material to the acctual system shouldnt be to much
and correct me if im wrong but i believe the general rule is 10hp for every 100 lbs
