Works ok. I bought a case to eliminate the road noise in my daughters car. I sprayed all 4 fender wells and the bottom and sides of the trunk. It did help but not as much as I was hoping it would. It took 1 can per fender well and 2 cans in the trunk. It looks great just wish it had more sound deadening capability.

I really like this product. This is the second time I’ve ordered a batch of it. It goes on easily, covers uniformly well and dries quickly. I use it to coat the fender wells of my 72 Chevelle. Took 1 can per well for complete coverage. Previous order had extra spray tips per can which I thought was a nice touch but this one came without. Ah well.

There were lots of reviews that says this product smells bad. It’s not worse than Rustoleum’s Undercoating you buy at Home Depot. So this statements has no merit. Second, it’s unlike Rustoleum — it’s much thicker in consistency when applied — which explains why it has such good sound deadening properties similar to applying Dynamat Extreme or Fat Mat — places where it’s difficult to apply these type of materials — for example under wheel wells where most of the road noises comes through to the cabin on my 2016 Sprinter 2500 — I am literally sitting on top of the wheel well! Overall, I am happy with this product and I recommend highly.

I bought this product not sure if it would do the trick, but it seems to be exactly what I needed. I was trying to dampen sounds coming from our nursery at church. The biggest culprit seemed to be the hvac ductwork that amplified any noises the kids made. So I took apart the ducts, sprayed a good layer of Boom Spray, sprayed some more, and even before insulating, the sound was vastly decreased.

Could not get a single can to spray for more than a minute. I ended up throwing way more away than I used. I would not recommend.
