Does anyone out there have experience with spray-on sound damping materials (like this)? I'd hate to replace the door speakers and still have rattling to deal with. Any recommendations? -pat

Hey! I'm new here, I have a 2010 Insight LX, and I'm planning to replace the factory installed speakers. So I'm wondering if removing the door panels and replacing the speakers are hard endeavors, or if if they're easy tasks. Also, do you guys have any tips for me since this is the first time...
