Looking at a quick solution to test some new speakers before I tear apart the whole car and do it right. Will PnS do ANYTHING to deaden sound? Or is it likely only going to serve as a door sealant. Tried a few other methods of sealing on the cheap, with negative results.
Even if only used for sealing, how long is the smell around?
Also. Is asphalt PnS traditionally used? or butyl/rubber
