Thanks for the extra info RAD, im just a diy'er so dunno the best way to do things lol.

I forgot to mention cutting slits to let air pockets out ill update the diy when i get a chance, thanks for that.

I did mention you can use less dynamat i just like to overdo things

My trusion bars were attached quite well to the panel so i let them be, the braces on my roof were a bit loose tho so i sikaflexed them to the roof skin while i was dynamatting the roof.
