Popular Jeep Treatment: Spectrum Liquid Sound Deadening

JEEP Wrangler Sound deadening

Spectrum liquid sound deadening has been the go-to product for many Jeep owners for the past 15 years. Because Jeep designs tend to be both really loud and really open, a Spectrum spray on application is a very easy and effective solution.

Spectrum is a water-based acrylic polymer that will stop vibrating panels dead in their tracks, reduce heat transfer, and even lower tire noise when used in the wheel wells. Spectrum can be brushed, rolled, or sprayed on. The average 2-Door Jeep will take about 4-5 gallons for the interior tub (or the full undercarriage). Sound deadening a 4-Door Jeep takes 5-6 gallons. We recommend that Jeep owners apply at least 3mm of total thickness (2-3 layers) to combat the unusually loud tire noises often found in Jeeps.

For premium sound and thermal insulation, go with our Jeep Build Package. The package has Spectrum Spray on Deadener for the vibration damping and heat transfer plus a layer of Luxury Liner Pro mass loaded vinyl to block out the airborne sound waves from the road noise and engine noise.

Like we said... 15 years of Jeep soundproofing. Check out the early 2000's microphone and the grainy video quality, lol. This vehicle is one of the very first Jeeps to ever receive Spectrum liquid sound deadening. Right around 2004/2005.

Part 2 of the Jeep Build - Damplifier Pro is used on the interior metal. Then Luxury Liner Pro added on top as the barrier layer to block out airborne noise. You will have the quietest Jeep on the road if you take this approach.

More Jeep Soundproofing Strategies

Spectrum sound deadening is used in a wide variety of ways, depending on the Jeep and what the owner is looking for. Here's a couple more pics that give you an idea of what your project could look like:

  • Jeep #1: This Jeep owner sprayed on Spectrum to sound deaden the Jeep's entire interior tub. After masking, this strategy is very quick to execute and looks awesome.
  • Jeep #2: Spectrum was rolled on with a paint roller in this Jeep. It's just as effective as spraying on for people that would rather not mess with a spray gun.
  • Jeep #3: Sometimes you just want to add some flare to your Jeep. This project turned out awesome - functional and gorgeous!

Jeep #1: Spray on that Sound Deadening!

JEEP Sound Insulation

Jeep floor after (3) 1mm layers of Spectrum. 2mm is the minimum suggested application. For any vehicle with aggressive treads, we recommended to get to at least 3mm of total thickness.

Jeep #2: A Roller Works too!

JEEP Liquid soundproofing package

Spectrum is just as effective when applied with a roller. When rolling or brushing on, you have to be extra careful to stay at the 1mm layer. If you apply it too thick and don't give Spectrum enough time to cure between layers, it can result in cracks. It works great, but take your time!

Jeep #3: Adding some Style

JEEP Sound Deadening

Some customers like to add a little extra Spectrum to the outside because it looks so good! If you want to apply Spectrum to a high gloss surface like this, you will need to scuff up the metal and apply a primer for Spectrum to make a solid bond.
