    Dynamat Installation

    Ok, so I'm installing my very first Dynamat install, and I've got some questions about it...

    I took off the liner, and removed the black-sticky stuff w/ my hands.

    I then cleaned off the black residue with naptha, and cleaned everything w/ denatured alcohol.

    I just did the driver's door last night, and it took a lot of time for me to do. What I did, is hung the dynamat on the door w/ masking tape, then cut out all of the holes, levers, things like that.

    Then, I peeled off the backing, and little of liner lined up to the holes that I cut..

    All in all, it took me about 1.5-2 hours to do it (and this was for one sheet). Just wondering if anyone had install tips on how to do it.

    So, I'm looking for tips on how to dynamat.


    Also, I'm going to do the inside of the door (the skin nearest the outside of the door), and there's a buttload of green grease in there. I started using some denatured alcohol and it appeared to be taking the paint off as well.

    Is the alcohol something I should *not* be using, or just ignore the fact it's stripping the paint?

    Can't speak for the dynamat install, but as for the alcohol I wouldn't worry about any paint you might remove. You are, afterall, going to be covering it with the dynamat anyway so you'd never see it again regardless if it's there or not. The alcohol would no effect on the door itself, so no worries there either.

    dynamat is HEAVY sound insulation.

    But, I guess if you are going for a kick ass sound system, then weight isn't your first concern.

    Dynamat = name brand and too damn expensive
    You can get much bigger rolls Mastic 0.075" 36" x 40" 0.05 -20 to +160F 0.4 Black 9709T21 $17.94.


    Go to www.mcmastercarr.com and do a search for High Temp Mastic....This stuff rules

    Much cheaper than Dynamat and just as good. Just be sure and buy a heat gun at Home Depot for like $30 and a roller.

    I've personally heard too many different things about the RAAMat, and all that other mastic/pseudo-dynamat products. I can afford the price for the extreme (it's really not *that* expensive), and it's tried and true. Been around forever.

    My $0.02

    Otherwise...

    So, when I put the dynamat in, I cut out the larg holes in the door from the dynamat. Looking at some other installs, few/no people are doing this. So, now my question is, should I go in and re-cover up those holes, or just leave it go. My reasoning, is that if I ever need to get into the door to muck w/ the motors & stuff like that, I can do it. If the holes are covered, I'll have to cut them out anyway.

    So, holes or no-holes?
