its in the ICE board, so think about Audi purposeVery nice. Why are you doing sound-proofing? Is the car too loud for you?
That's why you don't use tar based products Use a butyl based product it is safer and more heat resistant.Kudos to you. I did that on my Civic and had an unfortunately long hot week and the tar loosened up on the inside of the door and stuck itself to my passenger window. I couldn't roll the window up and it left one hell of a mess!
first the roof is way much easy to access than the floorti the op: youre better off putting mat on the floor or firewall than the roof, youll notice more improvement in those places than the roof.
And that's when the roller comes into play right? I've always cut bubbles out of stickers, but I wouldn't think that would work as well with dynamat.you dont need a professional training but you will need to know how to disable your car interior safely, lots of time and patience, you might take several more hour than somebody use to it and dont do it as well
the down side i will say will be weight gain but dynamat weight 0.45lb per sq ft... so you can put 80sq ft (a lot) for only 36lb
you need to do it without any bubble since condensation might form in the bubble
