I just bought and installed Dynamat Extreme and Dynamat Superlite in both my '32 Ford and my '69 GTX. I am very impressed with how it bonds to the painted steel, and it bonds very well to just primed steel as well.

I talked to several interior upholstery companies at the NSRA show in Columbus, and they all told me not to waste my money trying to save money on other products. They also told me that the bonding material will literally soak into and become part of the steel.

If I am already spending big bucks on my classic cars, why not just by the best and be done with it.

My 2 cents, Mark
