Alright here is my review of Alpha Damp, this project was to deaden my roof in my 2009 Honda Fit Sport. The car had a lot of windshield flex (well a lot to me) and I wanted to cut down on the flex and the rattling on the inside of the car. My weapon of choice for this was Alpha Damp, the product arrived in Early Feb however due to a car accident I had to put off doing this project till my car was repaired and returned to me. I got my car back on March 22nd and then after SBN weekend I finalized my new enclosure and set my eye's on doing the Alpha Damp to the roof.
So to start off I had to remove my entire headliner which wasn't the easiest task but it wasn't the hardest headliner I have removed either. Once that was removed here is what I had to start with.
And here is what I began with in alpha damp!
So I started off at the front of the car working my way back, after getting the first strips installed I could tell there was a difference in tone already as shown in this first video and photo.

I then moved onto doing the rest of the strips in the car which because they were pretty close in size the alpha damp I had a lot less cutting than I first thought I would. Alpha Damp is THICK, even my titanium Fiskers scissors had a rough time cutting it but I managed to get it work out well.
So I got all the main strips installed and here is a picture and video on the progress.

So I pressed on and finished up getting all the Alpha Damp in the coverage I wanted, I had 2 sheets left over when completed. And here are a couple photos and a video as I completed the installation of the Alpha Damp.

So after getting all the Alpha Damp installed I took a small break before re-assembling my headliner. I then got the headliner and all panels etc back into the car and did the exact same test I did in the first video you will see below, same song, same volume and the difference is very apparent!

Overall impression is Alpha Damp is awesome! The product goes on easy, fairly easy to cut considering the thickness and does exactly what it should. I wouldn't hesistate to recommend this to anyone looking to lower flex and rattling in their vehicle. Total install time from start to finish was about 4 hours, however I was working alone so with help this could be done in a couple hours I am sure!
Thumbs up to Alpha Damp!
