Lu I haven't had a problem using the regular Dynamat in the roof in both Hornet's. The yellow one I did 4-5 years ago and the orange one 1-1 1/2 years ago. I put it in as a sound deadener. I also put it in the floor in the interior with the Dynamat Extreme on the drivers side of the floor on the orange car as it is where the exhaust for the 6 cyl runs. I used the Extreme as a heat shield and sound deadener. The Extreme is some expensive stuff but worth every penny in my opinion. Today is a week I had my fall and am 90% recovered. It could have been worse and I could have broken some bones. I hope your mother makes a speedy recovery. A close friend just had a knee replacement and is home from his rehab stay. "Doc" Yahoo!
