Takes about 2-5 hours to dry/layer depending on the temp. I was working under the car with a heat dish but the air temp was hovering in the 50's.

I was working under the assumption that the resonator moves the standing wave (drone) out of the cockpit to behind the car. I started out by dynomating some easy to get to areas where the resonator was and just in front of the evap canister and some transaxal tunnel. This made a BIG cut in the drone but then it came back. I found out a month later that some of the dynomat had peeled back so I decided to use the quietcoat. I cut out the weak area of dynomat and then just 3-coated over everything I had done and whereever I saw bare metal. I used the grey color and it drys to gunmetal.

I covered the holes in the frame beams above the muffler cans with dynomat and 3 coated over them with dynomat. There is also bare metal in the rear wheel well where the softtop drains into.

Overall I used about a little more than a pint but I think this was because I used alot of dynomat as my first layer. The heat from the exhaust tubing on either the dynomat or quietcoat was a non-issue.

I have an alpine that at 70 mph I was at the 22-24 volume range. I now am at the 19-21 volume range but I typically turn off the music because the exhaust note from BEHIND the car is beautiful to listen to.

I might put on 3 more layers to what I already have done when the weather warms up.

 

As a side note to the rear tray area, I had dynomated and foamed that area and the entire trunk and got a 'small' improvement to the drone issue. I did notice that there is a wiring duct that dives down to under the doorsill just in front of the rear wheelwell that could act as a acoustic tube for the drone. If I ever get in the mood to remove the carpets, I'll get the underdoor sill also.

I think honda did too good a job of quieting the stock exhaust and left alot of undercoating off to give a little rumble to the car. This would explain why the same exhaust on different cars can sound louder on some than on others.

 

subscribing.

 

Here is the one I purchased... Cost $10 and could be designed much better even though I broke no clips.


Here is a pic I took during the process... I used an empty milk jug that i cut the top 1/3 of off to pour the Quietcoat into. This was a good container because I left the handle intact to hold while gooping in the trunk.

P.S. No, I am not a hand model on the side

 

Thank you Primo for the picture of the tool. Now I know exactly what I will look for tonight.

I could not find anything like the one in your picture at either Pepboys or Autozone yesterday. I went home last night, tried to remove one clip with a flat screwdriver, it did not work very well. I will try to go to hardware store or another autopart store to find the right tool as your.

Another question, my Quietcar jug was only 3/4 full, isnt it suppose to be 1 gallon and should be filled to the rim ?

 

Mine was filled close to the top... maybe 9/10ths full.

 

I pm'd you and put a picture of the tool in my S2KI album at https://www.s2ki.com/forums/index.php?act=m...d=si&img=204688

I hope this helps, the tool is very common, it may be called a GM door panel removal tool.

 

The "interior trim tool" that I got looks identical to PrimoAP1's. I got mine from Pep Boys. Incidentally, I got literally the last one on the shelf. Maybe it's not stocked very well.

 

Thank you guys for your inputs.
I could not find "interior trim tool" at either PepBoys, Autozone or Kragen, but I found similar tool at ACE hardware store near my house.
Since the Quietcoat is very thick, I used the heat from the engine to warm up the container while I removed the trunk's liners. It took me about 20 minutes to remove the liners and broke 3 clips in the process. I, then apply the first coat with very warm Quietcoat, it took less than 15 minutes. I put the Quietcoat container back to the engine bay to kepp it warm, took out the fan and set it at medium speed facing the trunk to speed up the drying. Had dinner, 30 minutes later the first coat was very dry, apply second coat after turn off the fan. Turn on the fan after second coat done. Took 30 minutes brake, applied third coat. The total time from removing the trunk's liners to finish third coat was 2 hours, using about 1/2 gallon. I did not have a chance to drive the car at highway speed to see how effective the Quietcoat in reducing the noise. I will try to apply the Quietcoat to under the car at around the seats this weekend.

 

It took a full 5 days for me to notice the complete effects this product offers. The cabin did sound moe quiet at first but got substantially better over time.

I applied to the rear wheel wells and inside the trunk only.... I am very happy with the results but may do the transmission tunnel and diff area as well. I won't be doing under the carpets or doors as I feel at this point it is overkill.
