sound deadening complete

soo i did my doors bout a month or so ago and didnt have enough mating to finish the rest so i put it on hold for a bit. bought some more mat and slapped it on about a week ago or so. just got around to uploading my pics today so here they are. goof looking first guy is a friend; guy with glasses is me

i took these door pics over a month ago, since then i also added baffles for the speakers and mated over the huge hole.

you got the bose system in there?

did you clean the surfaces and put the mat down with some heat? if not WI winters are going to play hell on the Dynamat.

surfaces were cleaned yeah and the day was hot enough that i really had to do it in my smallass garage. i think it'll be ok

He put down dynamat extreme. there is no need for heat when you put down a butyl based deadener.

in Georgia, probably not. but in the cold north its good insurance.

clean and de-greased/oiled is the most important thing.

butyl doesnt have the same properties as asphalt. what would be the advantage of heating up butyl?

Asphalt- heat is required (pretty much). Butyl- total waste of time.

a little heat helps get it stretched into close quarters and helps get a 100% seal along edges...sure, its not NECESSARY. its not a waste of time, it actually speeds up a proper job. plus, in a high yeild shop in december in ohio, it does become necessary.

I agree with you IF the deadener is asphalt. but butyl is no where near as sensitive to temperature as asphalt. plus cold is not the force that will break the bond to the body panels its heat that will degrade the bond after installation.

im not disagreeing that asphault is more helped by heat. ive just seen mat jobs (regardless of the mat material) turn out alot better and last longer if properly sealed. its not so much cold, as condensation between the mat and metal...hot, cold, hot, cold, water. Hell, if you watched some of the original Roadkill instructional videos, they wanted all seams and edges caulked...and it was one of the first butyl products.

There is no chance of water getting behind a properly installed mat. and a properly installed mat is achievable without heat during the install process.

How is heat during the install process going to speed up the process? if anything it will slow you down because you have to wait for even heat across the mat surface.
