Years ago when applying Dynamat to my Camaro I was told it is risky to do the doors. That the product would not hold and would "slide" downward. Is this true? I am doing a Chevelle soon and would like to know. Also, I noticed Malitude has Dynamat inside the doors.

I used dynamat extreme on my doors with no issue. 10 years and no movement yet. Ron
