i took the carpet out of my truck sanded down the floor board and put down a layer of herculiner (do it yourself bed liner).

i want the floor to be good and sound deadened but still want the bed liner durability.

i know i could put several more layers of herculiner and it would work fine as a sound deadener, but i`m looking for a more cost effective way to achieve the same goal.

any suggestions?

i was thinking i could put down a gallon or two of liquid deadener followed by a final layer of herculiner but i don`t know if the two would mix well, or how cost effective that idea is eather...

thanks for your time . -Dave

ANT at Secondskin is really good with coatings and how they work with each other. just email him at their website.

Glad to chime in on this one.
The hurculiner is a very strong paint with bits of 40 mesh solids added for some texture.
Good stuff for sure, but even if you loaded up 3 gallons of the stuff it would not reduce vibrations.

The coatings that you see online like:

Quiet Car
Cascade Audio VB-1X
Stealth Kote
Spectrum
Sludge

These are all elastomeric coatings from an acrylic base. They actually convert the vibrations in to low level heat. This transfer of energy goes from audible to inaudible once the product is cured.
This transfer of energy is something that the bed liners are not able to achieve no matter how much you load up on.

Your best bet is to use the noise coating on top of the existing bed liner product you have. You are lucky since you used Herculiner. This is a very thin product. They give you 1 gallons to treat an entire bed of a truck which is nothing really. A professional 2 part system will take about 3 gallons, maybe 4 for a bigger truck. The more bed liner you have down, the less the noise coating will be effective at killing resonance in the sheet metal. Your thin layer of bedliner should not interfere too much with the nosie control.

many of our Jeep customers do exactly what you are talking about.
They use the coating first, to kill noise, then they apply the bed liner on top of the nosie coating, once it is cured. This way they get the noise reduction and protection as well.

Applying a barrier on top of the damper will get you the best noise reduction results, but this sound more like a project that is, rugid or somewhat raw. Doesn't sound like you are going to put the carpet back in.

Hope that info is helpful

very helpful!!! thank you very much, i received your email as well i believe 3 gallons will work fine, yes i plan on doing the ceiling as well but am trying very hard to keep the cost down as much as possible.

someday within a few months the entire truck will be noise free, then i can begin buying equipment, i`m trying to make it deadened as well as possible first,

Because so many times before i would always get over anxious and skimp on the installation, cause of great deals on great product and just wanna hear it now.

no the carpet won`t be going back in, this truck is going to be quite the project.

thanks again!-Dave
