anyone have some tips for doing it quick. I got 3/4 of the firewall done including a small part of the tranny hump in 2 and a half hours and it is tedious boring work

Tips:

Its tedious and boring, beer helps

Warm weather helps. If its cold try storing the dynomat in the house before application

It doesn't need to be installed 3 layers thick like the audio forums show

I like to pull the backing off about an inch at first then remove as its being installed to prevent accidental sticking

Measure twice, cut once. then swear and cut again, see tip #1

Really sharp scissors work well for odd shapes

dont be afraid to put in a relief cut, it doesnt need to be water proof so shape it like fabric

Dynomat makes a $10.00 wooden roller, if you don't have one, get one. It makes laying it much easier. I precut the pieces, relief cuts and all prior to removing any backing and when I do, I do like Kurbycar32 stated, roll back a little at a time, roll it flat and then remove a little more backing. I find that it takes about 2 beers per sheet, just a reference of course.

Bit late now, but for the next person who finds this thread, I've had excellent succes with a product called "B-Quiet Ultimate" from

Easy to apply, forgiving during install, and very conformative. The cost is also much easier to bear.... And it works. They have a full line of sound control products. I have used their stuff on several projects now, including my own. Only down side is getting it off when you later find some rust repair that needs to be done. Don't ask how I know....

Love the beer speed reading for this job...I can now understand how much time it will take to get this job done.

......The cost is also much easier to bear....

Did you mean: "The cost is also much easier to beer." ?

btw I always wondered why soundproofing smelled like an old bar floor.

I used Megamat that was made out of butyl. 100% synthetic, sticks perfectly and zero smell. The traditional dynomat is made out of basically roofing tar so its got a bad reputation for stench. Butyl is also completely air-tight once its adhered so it should in theory make it impossible to rust from the inside. Just to be sure though i coated the interior steel with a rust proofing paint

i think i am using either rammat or fatmat not really sure has been about a year since I bought it...I do have the roller and have been using cuts to make it lay flatter ...thanks everyone for the input. cant wait to be done with this boring yet necessary task

Assembly beer is necessary in these kind of jobs. Or cider.
