Ceramic Insulation Heat and Noise Reducer- 1 Gallon - Sound Control and Deadener for Cars, Trucks and Audio Noise (HNR)

I put on a lot of light layers, and frankly it worked perfectly. Heat reduction is apparent, and even the wife notices a great improvement in noise from the 35's. I feel that you need to put on multiple layers to have it work properly. There are very specific thickness guidelines.

Needs to be thinned and filtered to spray but overall worth the effort. A small piece of tight hole hardware cloth and an old funnel worked fine. For the price it's well worth the effort at a 3rd of the price of other products.

Al's was great to work with, their customer service answered all of my questions promptly via email, and I really like the Al's Liner that I put in the floor of my Jeep Wrangler (TJ).In addition to the Al's Liner, I used this Al's HNR, as instructed, I actually applied it just a slightly thicker than the recommended "31 Mils" in the hottest spots of my Jeep's tub, the front floor pans and transmission tunnel.I measured before and after temps of my Jeep's floor, ambient temperature and the Jeep's surface temperature were roughly the same, before I let the Jeep idle for approximately 30 minutes and then checked temperature, before and after applying Al's HNR & Al's Liner.Max temp of 136.5° F before coating, 133° F after coating, and the Harbor Freight thermometer I measured with has a margin of error of +/- 2% so in reality I could be seeing less than 1% lower temps than before coating.Basically no difference in temperature. For sure not enough for the amount of effort involved.I can't say if it did anything for noise, since I covered it with Al's Liner, and I'm sure if there's any significant noise reduction it's from the Al's Liner, not the HNR. The Jeep is a soft top with over sized tires, so it's not exactly quiet going down the road, even with the Al's Liner.If I were to do it again, I'd just do the Al's Liner and skip the HNR all together.

Yes, it soundproofed my car and was a good value for the price.

Story of two products that claim to do the same thing. Al's HNR and Lizard Skin. In applying Lizard Skin I found all claims and descriptions spot on. The noise and thermal insulation is more successful than I hoped. But Lizard Skin HAS to be applied with their proprietary gun. I decided to try Al's HNR for my doors because of application options, spray, brush or roller plus it cost less. The HNR arrived promptly, I was stymied that there was zero instructions provided, none with the product, none on the website that I could find. After applying the product it just didn't seem like something was right. I hoped that it would change texture after application. 24 hours later. I basically have the interior of my doors white washed. No insulative effects that I can measure (in contest to the Lizard Skin which shows about a 40* difference). As for sound muting - nada, nothing. The metal still sounds like a tin like bell. Perhaps I got a bad batch. Perhaps had I had instructions I would have changed application or done something different. But few products have made me feel as ripped off and foolish as my Al's HNR purchase. Two stars as opposed to one star simply because it did apply and clean up well. If AL's HNR wants to contest this and offer me a second try, I would objectively give it another shot with some instruction. Otherwise, it is hard for me to not see this as a gimmick.

I was really looking forward to receiving this product and for some reason thought it was black. But when I opened the bucket the product was a light beige color - a surprise. But as I needed the product I decided to use it anyways. Overall seems like a good product, but it seems like a top coat is required over this. Maybe not so durable on it's own? I put two coat on the inside of my ford Bronco and on the second coat which I put on really thick, I could see cracking along the floor ridges. So use the old rule that more thin coats are better than fewer thick coats. Then as the product does not seem to be that scuff resistant and since it was not black like I wanted, I coated over the entire product with Truck Bed liner paint that I got at Harbor Freight for $44 a gallon minus an available everywhere 20% off coupon. Putting the Bronco back together this week so hopefully this product works for noise and heat.

Old 69 VW bus was just oh so loud this is a great deal is worked very well. If thisan ok color for you I would say jump on this is a good deal. I jus twisted it was packaged a little or lot better the seal was more then broken ,and the box well let's say it was I'm sound proof. ;)

Went on really easy. Did like 5 coats on my Jeep floor and transmission tunnel. Seems to have helped. I bedlined Interior and I can touch the floor and not burn myself. I can't speak as far as noise reduced. I wish I had done a decible test before and after

It's OK, but not what I thought it would be, it's water base and that's the biggest issue,
