    tried putting some sound deadening material on the roof of the car (not going to say the manufacturer because everyone has there preference). Well, its not sticking! I took a torch to it just to heat it up a bit and really try to adhere it but after a couple of cold spells it came down. I tried rolling it on, cut open all the blisters and rolled the air out of them. What else can I do? I really would like it on the roof just because of how thin the metal is. Would doubling up on the material make a difference? :confused:

    Did you clean the metal before applying the sound deadening? Rubbing alcohol works good to clean it. Also, if its a really cheap sound deadening it wont stick as easy. Dynamat X-treme is pricey, but sticks easily.

    Clean is a MUST

    Use acetone or rubbing alcohol...it should stick for life if done correctly

    used acetone :confused: I'm wondering if it was because the metal was cold (applied it in the winter) and now that its warmed up a bit its affecting how it is sticking. I'm wondering if I can spray some 3M adhesive and apply it again :huh:

    yeah.. the only thing you gotta do is clean the surface with alcohol.

    AND use a heat gun or blow dryer to apply it.

    AND make sure its on there tight. no bubbles or nonstick patches.

    its really not hard. I've done countless cars, never had a problem.


    Good LUCK!

    I guess I'll do it over again. I used a torch, just waived it back and forth on the surface until it got mushy and the applied pressure. When I got an air bubble I would slice it open and force all the air out. I'll try it again. I just don't want to put my headliner back in and have it happen again and possibly jam my moonroof.

    instead of cutting it. just use a rubber hammer, or a dynamat roller to really get that stuff on. Its hard work if you think about it, I mean you gotta keep rollling on the stuff to get it to be thin and really stick on there.

    can we ask what brand you got?

    that MIGHT be a problem. I've only used extreme dynamat, but I've heard other things work just fine.

    to me though... I rather use the best. and dynamat isn't the most popular for no reason.

    let us know.

    I actually got Stinger's version but it seems to be fine else where, just not the roof. I got a good deal on it when a local shop was closing down. Just enough to do the cabin of the car (floor from the firewall to the rear deck, rear quarter panels, and roof). Everthing else will be dynomat unless I find more stuff on discount. Still have to do the doors, rear quarters, and trunk.

    sounds awesome.

    I figure as long as it's not some cheap flimsy home depot stuff..


    anyway. very cool that you're doing your whole car. May i ask why? just for fun? or do you have crazy ass system?

    a coworker of mine has an escort with two 13.5 w7s in a custom made box that replaces his back seat. so he dynameted his WHOLE CAR. i mean top to bottom. and its crazy.. you can barely hear his music from the outside. but the second you open something up. its loud enough to hear a block away. it really is a great product. and I wish i had the money and time to do my whole car.

    two reasons, I don't want to hear my exhaust and I'm doing a lot of interior work so I figured while I'm in there I might as well do the job right.

    The cold weather does affect it a little, but even when using Dynamat X-treme it still sticks without the use of a heat gun or torch.

    it may stick (this wasn't the initial problem or reason for using a torch), but trying to flex it or shove into areas is a pain if its been sitting in the cold.

    Yep very true. I recently had to do this in 20-30 degree weather. Even colder at times. :(
