Firewall is a water based acrylic polymer, loaded with heat reducing ceramic spheres and thermal insulating glass beads. When applied to the sheet metal panels of a passenger vehicles, Firewall will reduce convectional heat and will insulate the passenger compartment. 

More details

FireWall is a water based acrylic polymer, loaded with heat reducing ceramic spheres and thermal insulating glass beads. When applied to the sheet metal panels of a passenger vehicles, Firewall will reduce heat transfer and help keep the  passenger compartment cool and comfortable. FireWall Ceramic Coating is loaded with vacuum sealed fillers, making it flame retardant in addition to being non-toxic and waterproof. Easy to apply with brush, roller or spray gun! 

  • High heat, water based viscoelastic polymer designed for thermal insulation
  • Durable ceramic coating that's easy to clean up with water
  • Apply in 1mm layers to the recommended 2 to 3mm of total thickness
  • Excellent for any metal surface you want to protect from high temperatures (firewall, hood, undercarriage)
  • Temperature rated up to 400°F sustained, 500°F intermittent
  • Apply with a brush, roller, or spray gun 
  • Made in the USA

Product Usage Tips

  • Always keep a 2" air gap between FireWall and the heat source
  • Clean up with water within 30 minutes of application. Do not wait longer or FireWall will dry.
  • If applying multiple layers of FireWall, wait 30-60 minutes for the product to cure and change color from blue to black.
  • FireWall is designed to adhere to metal. Do not apply to plastic or fiberglass without the proper primer. If applying to a high gloss wax coat, you must sand down and apply a primer.
  • Do not freeze FireWall! If it does freeze, do not mix, shake, or move until it has completely thawed.
  • Wait 24-36 hours (depending on humidity) before putting upholstery back in the vehicle. Wait 7 to 10 days before painting or applying a bed liner.
  • As FireWall cures, its deadening properties will continue to increase. Vibration damping doubles from 4 hours --> 48 hours, and continues improving for 7 days.
  • FireWall contains rust inhibitors and dries with a seamless finish. It is water resistant and and solvent resistant.
  • Shelf life of 1 year when stored at room temperature

Application Instructions

  1. Remove loose debris, rust, dirt, and waxy oils to insure a solid contact surface. Most new cars will not need much prep work, while some older vehicles should be treated with denatured alcohol.
  2. Mask off the car for overspray. If applying to the interior, cover any mechanical or moving parts as well as wires and wire harnesses. If you don’t want to cover it in FireWall, mask it off.
  3. FireWall can be applied with a brush or with the Second Skin Spray Gun. The product will perform either way. Regardless of application method, the goal is to get to a total thickness of 2 to 3 mm. At a minimum, Firewall must measure 1mm thick to stop heat transfer (slightly thicker than a credit card). We recommend 2mm-3mm thick. At 2mm thick, 1 gallon will cover 20 square feet.
  4. Apply in layers of no more than 1mm at a time. If FireWall runs, you are applying it too thick. After 30 to 60 minutes (depending on temperature and humidity), FireWall should be dry to the touch and safe to add another layer.
  5. Most regular paint guns will not be able to spray Firewall due to the extremely viscous consistency. We suggest using a HVLP undercoating gun or the Second Skin spray gun. Whichever you use, the nozzle and stem must be 2mm.
  6. FireWall is easy to clean up with water if done within 30 minutes of applying the product.
  7. Allow 24-36 hours before another product or upholstery is installed. FireWall may be painted after 10 days to cure.


Spraying is the most efficient application method to choose for coating irregular surfaces. Prior to spraying FireWall, everything close to the panel should be covered and masked off for overspray protection. For an airless sprayer, you want at least 3000 psi, a 0.019” nozzle, and a hose less than 1 yard long. If you use our Second Skin spray gun, we recommend an air compressor with 5-6.5 cfm and 50-80 psi. A 6-gallon tank is ideal. If your compressor is not strong enough, try elevating the bucket higher than the gun and let gravity help out.

Brushing is the more popular choice for applying FireWall. Simply dip a paint brush into the bucket and paint FireWall on any metal panel that needs heat protection.


What is the difference between Spectrum & FireWall?
Spectrum is a dense polymer designed to damp lower-frequency structure borne noises. While it provides thermal insulation, its primary purpose is to stop metal from vibrating. FireWall is much lighter. The key ingredients are loads of extremely small glass spheres that are very poor conductors of heat. FireWall Ceramic Coating is not rated for vibration damping, as its primary purpose is thermal insulation.  

You can use both products together. Apply Spectrum as the base layer (at least 2 layers, 1mm each). Or choose one of the materials two depending on whether your focus is sound or heat. FireWall is excellent as a heat shield!

Weight per cured gallon = 5 lbs
Coverage: 1 gallon = 20 sq ft @ 80 mils thick (80/1000) or 2mm

Whether you are looking to quiet down your hot rod, or make your daily driver comfortable as a luxury car, Spectrum has proven to be the most popular & most efficient coating on the market.

Here is a quick lesson: 

Much of the reducible noise in any car is structure borne, meaning it comes from vibrations, like a wind chime. Unlike wind chimes however, our cars are not tuned to any specific musical frequency, so what we end up hearing is the road noise, engine rumble, and exhaust drone.

Stopping the vibrations on your cars metal panels is much like stopping a noisy wind chime with your hand. Once the vibrations stop, the noise stops.
Firewall is designed primarily to insulate from heat, but it kills virations in a very similar way as well; It stops the cars sheet metal from vibrating, thus, killing structure borne noise.

Firewall's key engredient, microscopic glass spheres, offer firewall an amazing level of thermal insulation. When applied at 3mm thick (about 3 coats) Firewall will insulate up to 200 degrees Fahreheit. 

What is the difference between Spectrum & Firewall?
Spectrum is a dense product designed to absorb lower-frequency structure borne noises, as dense materials are more effective at absorbing vibrations and sounds. Dense materials, however, are much better at conducting heat. Firewall Is much lighter, the key engredient being a load of microscopic glass spheres which are extremely poor conductors of heat, making them more suited to thermal insulation

How long does Firewall take to cure?
Like all water based products, Firewall will take 30 full days to cure but will be dry to the touch in 30-60 minutes depending on the ambient temperature and humidity.

When can I put my upholstery back in place?
We suggest that you allow a minimum of 24-48 hours for Firewall to dry before reinstalling your upholstery.

*Firewall is water based and will not adhere permanently to plastic or fiberglass without first using a self etching primer.

*Application surface should be dry and free from rust, oil, dirt and debris prior application.

*Do not freeze and thaw more than twice. If frozen, do not mix until completely thawed.
