spray on dynamat

[caliraised]

anyone ever used this before or know how good it works as opposed to the regular dynamat?

i read about it, i was told alone it doesnt work at all really, but can be a good addition to dynamat or something else in the hard to reach areas

its mainly used to seal speaker boxes and stuff like that, i also used it on the inside of my door panel due to all of the contours

I used it back when I had my single 12 and it did help a good amount of the rattles. The key is to lay it on thick ( Dynashield suggests at least the thickness of a penny). If you have a big system, I definately wouldn't rely solely on it. Keep it for the hard to reach areas and what not.
