Bringing this back!

Im planning to embark on a similar endeavor myself, and i had one question, is there any reason not to use the material below, for the cargo area and rear wheel well cover? Im pretty sure this material is already in the spare tire area, why not use more? I dont plan to do MLV in the doors, and i defiantly would not use this, but do plan yo CLD and tessa tape the crap out of the doors.

You are correct, it is in the wheel well. Also under front seats in forward wheel well.

I adopted the sound deadener showdown philosophy completely so didn't consider the material.

I can't say that won't work but I would have to Google around to find differences between this and mlv. Keep us posted with what you end up doing with pictures.

You could always email Don @ SDS and ask him too.

Also wanted to say, thank you for all the work you've done so far!

But from what I can tell, it should act similar, and appears to have a better STC rating (especially one the manufacture that includes an additional vapor barrier). However, with the materials being significantly different, I wonder which is better at blocking the sound frequencies created by road noise. I know with the 2006 Mercedes S class, they use a MDF style wood (maybe fiberglass??) in their door panels, which makes me think a harder/stiffer material is better, but we shall see.

Ill let everyone know how it goes. I just really hope I dont have any moisture issues with this VS MLV.

Are you saying that you appreciate the outcome? Agreed, it was a lot of work.

Still have to finish one small area underneath the rear bench and floor behind front seats. Should help a tiny bit more.

Other large area is the firewall, which I don't know what to do to it without taking off the dash.

On my 2013 Fit i went in through the interior air intake on the outside of the car. The black plastic between the hood and the windshied came apart, and I was able to access the space pretty easily. I dropped in a couple sheets of MLV and it probably helped the most on that car.Maybe it might work on the CRV?

Just finished the front driver door, and the cargo area. Took 10 hours. But i also do not have a garage, and did the cargo panels in my living room (see below)

I gotta say, the CDL i used (Killmat) worked great, and after the 2 areas, i still have about half of a 36sf box left. I did not do a complete coverage of all panels with the material, but the driver door was about 90%-95% coverage, and the cargo area was about 25%.

The undercarpet material used for a MLV replacement SUCKED!! Was very difficult to cut without jamming up my scissors, and was not easily cut with a razor blade. My past experience with traditional MLV was very easy to cut with scissors or a razor. Also my MLV felt like fiberglass with how much dust and itchyness it created. Did it work? Yes. But i would not use it again in the future. Im not mad, only because it was 1/4 the price of MLV. But it was effective in dampening the cargo area. Also acted as a natural decoupler.

Only used about 1/2 of a single roll of tessa tape. there were many cables in the CRV that I felt would not rattle after I opened it up. The cables felt pretty damn taught, and were well isolated as is.

Unlike Mnestrud, i built the "MLV" on the plastic panel vs the body of the vehicle. For me it was simpler, and more comfortable. Working in my living room vs sitting in the cargo area of the car. But im sure either way would work. But with my past experience with the FIT, knowing where random bumps would be (Caused by bottle/storage holders etc.) was life saving working off the panel.

One lesson learned was the rear cargo area can handle more than 1 layer of 1/8" MLV. It could probably fit 2 or 3 layers if you really want to press the panel clips back on. But with one layer, it clipped on with no problem.

I did have a HUGE issue getting the cargo panels back on however! The rear seat attachment was a huge barrier of easily reinstalling the rear panels. Maybe im doing it wrong, but it took all my might, and pressing against the roof and opposite side of the car to get the plastic plane to pop back into place. Once the panel was past the seat latches, clipping it in was easy. Maybe im doing it wrong, but my god, it was a bitch.

Otherwise, i will continue with my passenger and rear doors when i get some time. So far the bass response is better, but only just. Not a huge difference, but im holding any judgement until i atleast get the front passenger door complete.

Just finished all of the doors, and the rear cargo area, and Ill say the mid-bass is defiantly more defined and feels more powerful. Feels slightly quieter, but most of the rough road noise is still noticeable. But this was pretty expected as its coming up through the floorboard.

All i have left is the trunk cover, but im waiting until i find some instruction on how to remove it because of how many clips there are in the middle, and i dont want to break my panel in half.

Overall, usage and tools I used are below.

36sf of CDL
1.5 rolls of tessa tape
100sf of "MLV" (still have plenty left)
Panel removal tools (Life saver)
#2 Phillips screw driver
1 roll of Velcro
91% alcohol
Paper towels
(2) Green clips

Last night I managed to line the bottom of the driver side with CLD tiles, and put a few layers of the carpet underlayment "relatively" easily. I just removed the bottom door trim, panel around the fuel/hood door lever, and the under panel of the steering wheel.I put 3 layers of underlayment and I dont think i noticed a bit of difference.

However, mnestrud is right, where the sound just becomes more pronounced elsewhere and overall the car still felt filled with sound. I was looking at the Accord touring the other day while getting my oil changed, and the entire underside of the vehicle under the driver side, and the entire wheel well was lined with felt material. That might explain why the Accord is a bit quieter. However the Accord is not a "quiet" car by any means.

At this point, i am at "polishing poop" mode. Im not sure how much more ill do, But if i get bored one weekend, i might revisit it.
