Does anybody know of an alternative to luxury liner pro? I have been looking around an seen everything is about the same price. Just wondering if there is any cheaper (in price) material that would do the same job. I had looked into ergo matting cause i have a lot of it at work. Just cant walk out with a large roll of it. That ergo mat is made of the same composites as the LLP and i have already felt the differences just not in a car. Any options out there?

Luxury Liner Pro is a combination of a mass loaded vinyl fused (not glued) to a closed cell foam that acts as a decoupler.

Ergo matting is typically just rubber and doesn't have the weight or density comparable to mass loaded vinyl.

To replicate LLP, look for mass loaded vinyl that weighs about 1-1.5 pounds per sq. ft. and some 1/4"-1/2" closed cell foam (preferably a neoprene or nitrile type).

MLV can be purchased in a wide variety of thicknesses and weights and can be had from a ton of different sources. It's used a lot in the building industry too.

This will get you about as close as you can to a DIY version.

You can use ergo mat, I would just suggest using some that is a bit thicker, thus you get close to the same mass as most MLVs.

Thank you for this info was thinking i would of had to go a little thincker with ergo mat cause it felt a bit more squishy and not as dense as the LLP. I may end up going with the LLP anyway it seemed to have a better feeling product the some things i have compared.

Weigh all of the options out there. Some of the best products are those that are put together by the DIYer.

another question i have is... When i was redoing my speakers )front and rear) i had taken out everything the seats interior panel and the carpet. I had planned on putting some deadening material on all sheet metal areas. well after pulling up the carpet i noticed there seem to have been a factory type of vibration dampening material on the large areas already. I was wondering what would be the best solution for this?? The sludge material or they water based spectrum?

Some photos of what i mean... sorry for the poor pics my camera as been relly shitty lately.

edit: just wondering what i could do cause it has beads like that throughout the whole truck. mainly the larger areas. Would that be fine and i could just lay some MLV over top of that?

You could just go over the sheet metal with MLV and you would notice a significant difference, but it is best to use some sort of product to control panel vibrations first.

That right there looks like some form of factory applied sound insulation or at the very least a seam sealant.

That would be classified at best as an extensional damper, not the best solution for controlling vibrations or panel resonance especially in that small of an amount.

So use of a vibration controlling product (be it mat or liquid) would be beneficial for the sheet metal before you lay down some MLV.

And yes both our Spectrum and Spectrum Sludge are water based. No fumes to get high on, easy to clean up, and packed with tons of anti-corrosive and rust inhibitors.

what would be the best application for this? The sludge or mat? I was thinking the sludge would be best this way i know it would get between the seams, or would there be no real difference with a mat type deaden-er? Can a mat type deaden-er stick well to the beads as long as its well cleaned?

Typically the mats have the upper hand when it comes to controlling vibrations (because of addition of the constraining layer).

I would boil it down your application preference. Do you want to cut, peel, & stick? Or do you want to spread it on?

The mats won't have an issue sticking to the previously installed material. The only thing I have not been able to stick a mat product to is an oiled surface.
