    Customers like the vibration dampener. They say it works nicely to mute vibrations in car panels, keeping the speakers from vibrating the doors.

    "...Easy to cut. Take photos first in case you decide to sell the vehicle one day...." Read more

    14 customers mention7 positive7 negative

    Customers are mixed about the weight of the insulation. Some mention that it adds weight to their car, while others say that it saves weight.

    "...Damplifier Pro is a good bit heavier than Dynamat extreme...." Read more

    "...After putting it back together it sounds a lot better. The doors feel a lot heavier and close with a heavy thump compared to before...." Read more

    7 box's of Dynamat in one pathfinder, no carpet, five gallons of Herculiner!
    5 Stars
    7 box's of Dynamat in one pathfinder, no carpet, five gallons of Herculiner!
    Herculiner - HCL1B8 - Brush-on Bed Liner Kit After deciding I would like to fix up and keep a 91 pathfinder around for a few years. I decided I was going to take out the 20 year old carpet. I was originally only going to use Herculiner, do it yourself bedliner (I choose Herculiner because of so many positive reviews). After many days prep; I removed all the factory sound proofing tar with a hammer and chisel, then sanded with a drill and wire brush untill all was clean metal. I applied two coats of Herculiner. It looked great and was solid. I decided I wanted a slightly thicker floor. So I purchased two bulk packs of Dynamat and laid a layer. It went on so easy and looked so nice I decided I should do two layers. I bought another two bulk packs of Dynamat and laid my second layer down. I then applied a final two coats of Herculiner. It looked great. I decided to go the extra mile and do a coat of optional Herculiner UV protection. I used a quart and a half. It was going on a purple gray and I assumed it would dry black and be unnoticeable. It did not. It looked horrible. It had not changed to black and had separated in areas and bubbled as well. I called Herculiner and told them my results. They were great, they said it sounded like I had got two from a bad batch that had gotten out. They offered right away to mail me some replacement bottles. They thought I should be OK if I sanded down the bad UV protection and reapplied a coat or two of Herculiner. So I picked up another Herculiner kit from AutoZone and went to work that day. I sanded for about five minutes and realized that the UV protection was not going to just sand off. So I spent about two hours sanding all the surfice with 80grit and cleaning up the sand it produced. I then applied another two coats of Herculiner. It looked real sad. I called Herculiner again and this time I sent them some pictures of how the bad UV protection turned out after sanding and two more coats of Herculiner. If I had no other options I might of been able to sand all the UV protection off. It would have took about 40 hours, I think though. I decided the only way I would have results I'm happy with was to apply another layer of Dynamat and then two more coats of Herculiner. So I ordered two more box's of Dynamat and applied one more layer. I then applied my last two coats of Herculiner. And it looks great again. I now know why Dynamat and Herculiner are the brands brought up the most online (forums). These products worked great together and are of the highest quality. Hercliner is sending me out some replacement UV protection that is not from a bad batch,( it should be a solid black, not purple). I will wait a year and if any of the floor fades apply some then.
