Just like the title says. " where is the best place to buy dynamat" for the whole car. The car is a 1969 camaro. How much? and Who has the best prices?
Cheapest I found was on ebay and I paid about $135 shipped for a 36sq ft box. Locally it was almost twice that. The shipping shocks the hell outta you cause most ebayers charge 35-40 for shipping for each box no matter how many you buy but overall it was still the cheapest way to go. I used 6 boxes on a 55 2 door sedan but that did all the doors, floor, roof, trunk, and sides. I think you should start out with at least four boxes and go from there. I'm doing a 55 Nomad and for the floor I used two boxes. HTH.
While I did not use dynamat, It took about 110 sq feet of Second Skin's Damplifier Pro to line the inside of my 68. I covered the doors outerskin and behind door panels, outer skins of the quarterpanels and behind the reas seat panels, firewall and floorboard. I haven't lined the roof or behind the sail panels yet, but I figure it will take about 40 more sq feet.
eBay always has the best prices on Dynamat.
Just make sure you buy the real Dynamat Extreme product.
There are lots of cheap knock offs on ebay that are made out of asphalt, which melts at 180 degree, is toxic, and has a foil that is half as thick as the foil on Dynamat Extreme and not capable of killing nearly as much noise and vibration.
