You still need to add insulation. That is not insulation, only sound deadener.
I would worry about a product purchased at a hardware store falling off in the summer sun.

Professional roofing suppliers do not sell junk to be installed on multi-million dollar homes, and neither will their competition who sell similar products. There is no concern about professional materials failing when subjected to heat. I have installed Dynamat supplied by customers and it has not failed, nor have less expensive products. Q-pads are another option, not to mention every sound deadening product available to a shop. Call a rep or ask a jobber. Many like the ones I use have display boards for comparison and application usage. I'm not paying more for a product because a vendor targets the hobbyist; many shops who know better will not do so.
I've had home products cooking in the sun for over a year and they are not falling off.
The insulation or deadener found on a 1967 will not be found on a new car. Times have changed.
What products have you used in your shop for restoration and collision work? I'm always interested in the latest available to businesses.
