I drive one of the tinniest vehicles on the road (next to a Neon anyways); a '94 Beretta. It has enuf power to push around a few more kgs of weight so it's time to quiet her down.

I have replaced my door seals and the 'whistling' is gone. Now it's primarily (from what I can gather) wheel/road noise and general wind noise over the outside of the vehicle.

Since my vehicle is a GM, I want to try and salvage all the parts that they decided NOT to rustproof by undercoating them anyways (like, rubberized stuff ... apparenlty the stuff that can be applied with a 'Shutz' gun??). However, talking with Dukk it's a little messy ... but that's not my concern. My main concerns are as follows:
1. Which will take more time (MAT vs. Undercoating)
2. Which will work better (reducing outside noise)

I will be deadening the doors with some form of MAT anyways because I "BELIEVE" I am putting 3-ways in the doors (I have the parts, I am just not sure if I want to sacrifice my door panels to the whim of my cutting ability).

As a random aside, anyone know what to do to 'seal' a door when a vehicle has a seatbelt in the door instead of on the pillar? Why GM did this is completely beyond me ... it's rather annoying.

I have doubled up the pocket-lint looking stuff under my carpet (factory deadening). It helped, but it has a limit. My Corsica had 3 layers under there; that was a pain in the butt.

Dukk already warned me about the rattle-can stuff, because it sucks; this I know. But, the crap u buy in the tub is apparently thick so it does a far better job. Looks like I will be doing the spray as my car has nothing underneath as far as deadening/anti-rust goes.

 

Stuff's expensive ... but if it's going to do the job right then I will be picking some up.

I have a claim in process with GCA (not their fault) so I have to deal with him again anyways.
