Not really, it will help soak up some of the waves, but won't do much to keep the metal from vibrating. It might even have a negative effect on your bass.

No! you will have to lower the resonant frequency of the pannel that is viberating.This is done by weight(dynamat,deadbeat etc. or add a brace to the pannel.

Also polyfill absorbes moisture so if it collects any type of water, which can happen in a vehicle from time to time, then it will soak that up and leave it resting against metal which causes rust which causes holes which causes your car to go faster, weigh less, but look worse. You must prioritize
