Weight Sensitive Sound Reduction

[GoodysGotaCuda]

I am curious to hear from those that may be in a similar boat.



My car has the entire underside coated with lizard skin ceramic/thermal coating, the inside is coated with raptorliner bedliner. I have some dynamat squares in a few areas of the floors and doors to help calm the resonance in the panel. I am not interested in adding 150+lbs to the car with dynamat.

I would like to hear if you have any other solutions you have found to help reduce the noise of a classic car without adding a ton of weight. Such as

• Different door vapor barriers [foam?]
• Wheel well/exterior sound absorption [high frequency tire noise]
• More strategic dynamat placement
• Fiberglass-like insulation
• Tricks for finding hidden openings in the firewall, door seals, window seals, etc.
