In most applications 80 sq feet is fine. Extreeme SPL situation would however call for more. Some of our xtra cab owners go with 160. Pretty common actually. ANT

There are a few things you can do. You can apply a radiant barrier under the Tahoe. This will reduce the heat that transfers through, in to the cab. This would be a great option because it will keep the damping mat cooler, which will make it perform better. The hotter the butyl gets the less it works as a vibration damper, so keeping it cool is ideal. There is not much you can do to keep the heat from coming through. These products, even with really thick foil layers are passive dampers. The heat will get transfered through, eventually. The thicker foil will slow the heat down for sure, but really, once it transfers in to the cabin, game over. We are working on a new product. Very exciting stuff. It is a thick layer of aluminum foil (10 mils) laminated to a thin (1/4") sheet of spun fiberglass which also has a high temperature adhesive on it. This product can handle temperatures up to 1000 degrees with as little as a 2 inch air gap, and turn it in to 200 degrees. It will turn 300 degrees in to 125 degrees. Imrpessive stuff! Stay tuned for more info on it! What you can do to keep the heat at bay once it gets through the damper is apply a produc tthat does not transfer heat very well. For this we sell a product we sell Heat Wave Pro That can go on top of the damper you have in place. Then at least the heat will not get transfered in to the cabin as fast. 1 layer will reduce the transfer rate by as much a 700% Let me know if you want some samples. ANT

Thanks for the comliments Tony! True. I am very excited to be here. The things we have in store for this place should prove to be a moral lifting experience. You following me camera guy? ANT

Sorry man.. No more pics. The upholstery guy finished the Luxury Liner install. Car is on the road now. I still need to check in with the owner and see how the interior turned out. Maybe I will soon, and snap some pics for you all. ANT

And a few shot after: We used 2 layers throughout the entire cockpit. Some spots have 3 layers. Even though this is a convertible, this is going to be one solid sounding machine. We can't do much about the wind noise, but the tire noise, engine heat and vibration control are all taken care of. What is nice about sound deadening, is that the mind interprets it a few ways. The less squeaks, rattles and resonance we hear, the more our mind converts that lack of noise, in to a perception of strength. To the driver, the car will actually feel more solid, and will almost seem to hug the ground better. It is really awesome how the mind perceived the differences, and a more stable and firm ride is just one of them. Thanks so much to Gary for letting me work on his awesome car, and to McCabe for allowing me to make a mess of his shop for a while! Also, thanks to you guys for reading this entire thread.

Here are a few shots of the cockpit before the vibration mat was applied:

This means we can add a second layer. The product starts out dark blue, almost grey in color, but once it dries it becomes black. It will start to darken after about 20 - 30 minutes depending on the temperature which is when additional layers can get applied. Many people will use Spectrum as an interior coating and exterior coating. If we were going to do this, the roadster would need about 5 gallons: 2 as and undercoating 2 in the cockpit 1 in the trunk We only used Spectrum in the wheel wells however and ended up applying just a little more than 1 Liter (1/4 gallon) per wheel well. Another shot of a wheel well coated: We took a break for a little while, so to keep spectrum from drying in side the gun, I detached it from the line and threw it in a bucket of water: This is a shot of Spectrum as it was starting to skin over. Notice it has already turned black? This one still needed another 15 minutes to dry. In 24 hours, the Spectrum will be pretty firm to the touch. In 72 hours it will be 80% cured. It takes 0 full days to cure, at which point you will notice 100% of the sound deadening results. Next project was the interior cock pit. For this we used Damplifier and Damplifier Pro. Damplifier Pro has a much thicker foil than regular Damplifier, so I used that up front in the foot boxes where heat is going to be a big issue. The first step was to vacuum out the interior. Gary had a handle on that:

We did this to all 4 wheel wells. In total we use up about 3 or 4 sq feet each. Next was the Spectrum. First, we had to protect the car from the coating. For this we use the few garbage bags around the brakes, and a roll of sell adhesive carpet plastic. This stuff is awesome for masking off areas of the car you want to protect from overspray. Once we masked everything off, it was time to spray the Spectrum vibration coating in the wheel wells on top of the Damplifier Pro: http://i446.photobucket.com/albums/qq187/S...f5100Medium.jpg This is a shot of Spectrum after a single coat. Spectrum is a very thick vibration paint and is set to a specific viscosity, so that it can be applied at 20 mils (20/1000th inch) in each coat. Apply it any thicker than 20 mils (1/2 mm) and it will either start to run or drip. So after we did a nice solid layer on each wheel well, we would simply move on to the next one. By the time we finished our first coat on the 4th wheel well, the first one had already begun to skin over.

Here is a shot the underside of the wheel well with nothing on it at all: And a shot with Damplifier Pro getting applied: Here is a full layer of Damplifier Pro in the wheel well:

For sound deadening and thermal insulation I brought the follow amounts of each product: Damplifier Pro Bulk Pack - 36 sq feet Damplifier - 50 sq feet Spectrum - 5 Liters (1.25 gallons) Luxury Liner - 36 sq feet (no time to install it so the upholstery guy is going to put it in) Heat Wave - 18 sq feet (upholstery guy is going to put this in as well) We were able to treat the entire interior with Damplifier and Damplifier Pro. We did a double layer throughout the entire cabin. I left McCabe about 40 sq feet of Damplifier to finish the trunk with before he sends it off to the upholstery guy where the Luxury Liner and Heat Wave will get installed. The one thing that took up a good part of our day was something I had not planned on doing until we got there. The wheel wells. After looking at the underside of the car, I noticed that Factory Five does not provide any type of barrier to protect the paint job on top of the wheel wells from the star patterns that sometimes happen when rocks shoot off of the tires and hit the fenders. Gary and I talked about it and agreed that we take every step necessary to protect his paint, so we jumped right in to it. I decided to use a combination of two products to protect his paint: Damplifier Pro - our self adhesive vibration damper Spectrum - Our water based vibration undercoating. Since spectrum is water-based it is not going to adhere to fiberglass or plastic very well. Water-based coatings work very well with painted, raw or primed metal, but when it comes to fiberglass they do not adhere as well. They will stick, but not nearly as long as if they are applied to metal. It is for this reason that I used Damplifier Pro first. Not only will the Damplifier Pro give us a nice solid vibration damping treatment, but it also has the thickness foil in the industry. 6 mils thick compared to 4 mils of our closest competitor. That allow for great protection from the rocks, and better vibration control in general. Since Damplifier Pro has a foil heat shield, the Spectrum will adhere to it much better than it will to Fiberglass. This gives us just one more layer of protection against rocks and help make it look real nice too. When it dries, Spectrum is black, and looks similar to a bed liner, but unlike bed liners, Spectrum is elastomeric, which is how it dampens vibrations so well. We also use a wax additive and a cryogenically manipulated polymer when making the Spectrum so it is perfect for use as an undercoating to prevent rust and corrosion or an interior coating to absorb noise and vibrations. Awesome stuff!

The reason I drove up to Chino Valley was to insulate the Roadster for Gary. By the end of the day we finished about 80% of the labor. Here is what I brought with me to kill the noise and heat in this beast:

And this is Gary’s Cobra. It has a 358 NASCAR engine pushing 817 HP. I'll try to get more details for you guys soon.

Next my attention turns towards the Corvette up on the lift:

So my day started off by driving from Anthem Az (20 minutes north of Phoenix) to Chino Valley, (20 minutes north of Prescott AZ) Took me about 90 minutes to get there: Me Driving Once I arrived I met the owner of the shop. Turns out we were at McCabe Racing. Formerly of Laveen AZ. This is the first thing I see when I pull up:

Thanks for the compliments guys! Looking forward to hangin gout here a bit more. ANT

Thanks for the reccomendations for Second Skin guys! I appreaciate your confidence. There are a lot of good dampers out there. A few have already been listed Raammat is good, the newer edead products are supposed to be a bit improved fromthe previous 3 or 4 versions. They seem to have a decent following of loyal customers. I think Hushmat is a sponsor of SMD and they have a killer product. Same goes for Cascade. Just be sure to stay away from roofing tape like peel and seal. There are a lot of companies out there that are selling P&S as a sound damper. Just renaming it. A good way to tell is the price. anything that is priced around $1 - $1.50 psf is most likely asphalt with a thin foil. Too thin to actually constrain the adhesive layer which is what the thick foil on a real damper is designed to do. Butyl based dampers with thicker foil usually cost over $1.50 psf to produce. Hence the higher price. Our Damplifier Lite just came out yesterday. Great product too. I don't want to hog this thread, so I wil just put it out there; if anyone has any question about Second Skin or sound deadening in general, feel free to email me at [email protected] or you can call my cell 623-533-8193. I am always happy to help regardless of which produc you use. ANT www.damplifier.com

Thanks guys! Glad to be a SMD partner. Can wait to get the ball rolling on things. ANT
