I was talking about on the inside of the plastic door panels. It didn't really sound like a good idea to me so I figured I'd ask first. Thanks for the pics and info!
I'm looking into tackling the sound deadening in my Suburban this weekend. Where do you guys recommend getting the closed-cell foam? I'm having a little trouble finding it. I also had someone recommend a layer of the 3M rubber undercoating on the door panels. Has anyone else tried this?
I know this thread is old but I have a similar problem with the headlights on my '96. They start up fine, but begin flickering after just a few minutes. Where can I find a Heavy Duty Harness? I see that LMC has one, is that the same thing?
