Works great, very hard to cut. The material shipped promptly, and arrived before the projected date! The product works as advertised. The only drawback is that is extremely difficult to cut. Perhaps you could include a sheet with installation tips and techniques? That would have been very helpful.

Sound Deadening Silent Running Paint Worth the Money! I just finished with two coats of the sound deadening paint, Silent Running,, over a sheet metal duct on the ceiling of a basement music studio. Unbelievable, the difference. WOW. Highly recommended. It also quieted down the air noises and echo in the upstairs bedrooms that the large duct feeds. Very effective paint.

I recommend using this material in trunk area over dynamat because light weight and more effective
