Works good.

I sprayed two gallons of this stuff. It goes on well, even with the cheap undercoating gun I bought for it. It leaves a nice factory looking finish. There is a small percentage of rubber chunks that do not stick but can be easily swept up once things are dry. It does seem to scrap off if applied over a gloss paint (POR15), but not easily. I scratched some off with the bucket seat brackets I was fitting in the car. Overall, happy with the product.
Arrived as described

The media could not be loaded. I was skeptical about buying this because of some bad reviews but I thought at least it would cover up my unprofessional sound deadening job I tried doing myself if it didn't work but it did. I hand painted 4 coats on and behind the wheel wells and rolled 2 good coats over all of the existing sound deadening material without a problem. I lightly prepped it with alcohol before painting on top of it and had no probably adhering to the metal or on top of my other material. I bought it to help reduce vibration for my music and to say I'm impressed is an understatement, it's pricey for a gallon but you definitely get what you pay for. I drove around with no music and can tell a huge difference just in road noise not coming from the back and now hearing things in the front of my car I've never heard before lol. I'm very satisfied with the outcome and almost convinced that my trunk is bullet proof now lol (jk) but would definely get more for my future projects.
No Harmful Fumes

I've used many sound insulating products. The one thing that always annoyed me was the fumes! This has zero to tolerable fumes. Which surprised me. The application is easy and effective. I applied 2 coats in the inner and outer inner parts of my door. Need to buy more for for the fender wheels. I should've bought this product a long time ago.
