Keep the updates coming! I almost did this last week and will eventually get to it.

If you put a layer of closed cell foam over the dynamat you'll get a much better result. Google "ensolite". It's cheap, light and self-adhesive.

Chuck, I think you just sold me on a kit from RAAMaudio. I'm thinking about purchasing the "Package 1" kit today that includes 37.5 sq. ft. of their BXT II sheets and 41 sq. ft. of their Ensolite.

That's what I used. It's not a bad deal at all.

That's awesome. Keep the updates coming.

Any recommendations other than the product itself? Install tips, things you'd try differently? Notice a good improvement?

It was a pretty good improvement. I just did the hatch and back side of the wheel wells. I've got a lot more to do in the future. It's fairly unpleasant to install since you're leaning over for hours, but it's not hard. Be careful with the deadener. The metal backing for it is SHARP. Wear gloves or it will cut up your fingers pretty bad.

Thanks, Chuck. I'll start with the hatch too and move to the doors next in the near future, as well.

Sorry for misrouting the thread, OP. I'll shut up and tune in for updates. :tiphat:

I put material on the middle divider.

Wow ... you still have a whole day left? I think I did my entire hatch in about 6 hours minus an hour or two for breaks. I was working from 12" squares though, so I did very little cutting until I was filling in the last areas.

By a day I mean 2 hours. I've worked total of 4-5 total. I think I'll need a couple of more to finish it.

Honestly, why put the plastics back in to pull them out again? You'll be much happier in the long run if you drop $50 on some foam before you button everything up. It does much so more than the dynamat.

My back would not have given me the option to do this project twice. Leaning over the hatch for hours gets really old.

you need to be a tiny little asian like myself so you can sit in the hatch comfortably :bowrofl:

it's pretty easy to install and easy to cut with a good pair of sheers or a sharp razor.

aside from what most people said i also suggest getting a roller to help press the product to the panel/surfaces. i improvised and got a bedframe wheel.

i'd also keep a pair of sheers/fresh razor handy so you can make cuts/adjustments as you are installing.

wear thin gloves if possible i found myself getting a bunch of mini cuts from the sharp edges of the hushmat

i have done my doors and rear hatch and i have noticed the biggest improvement in the form of no 'ding-ing' when going over gravel or dirt and less 'raining' sound when driving on wet surfaces. the actual road noise is mildly quieter but i wouldn't say it's super quiet like a lexus. that said i was able to hear my exhaust and engine (stock at the time) a lot more clearly. :excited:

Use some gloves or something. I cut my goddamm fingers 7 times( wish I was kidding lol). Use a small roller to press on the dynamat. You can also use a tennis ball for the weird curves. Start with the bigger pieces/areas first so the left over material can be used for patching. Don't be afraid to get in the trunk, I'm almost 6'"3 190 pounds and it was fine. Oh, dunt forget to pull the e break hehe

:iagree:

Also, the rounded butt end of a screwdriver seems to be the perfect tool to get in some of the smaller curved areas.

Here is the final result. It helps; now I can have normal convo in my car :)

Very clean. If you want quieter, go back and do the fenders. That's where a lot of the noise comes from. I used nearly 2 boxes of Dynomat. There is not an inch of bare metal showing from the seats back in mine.

Yeah, I know fenders let a lot of noise. I was so tired/impatient at this point that I couldn't care less about the spots I missed lol

A side note, I noticed the noise from the fender area as well, not as much from the trunk side, can we get better fender wells/covering on the underside or is the CCF on the fenders the best bet?
