How do you like the Noico Green CCF? I used Noico 80mil myself and was surprised at how good it went on and seemed to be legit butyl to boot.

100% satisfied with the value, ease of use, and effectiveness of both the 80 mil butyl & Noico green foam.
You’re right about perception as being part of how you personally measure the results. It depends on variables such as installed equipment (A/T tires for instance) and even the state of your hearing (I have tinnitus & other effects from jet engine exposure, but the results I’ve described are relative to before adding deadener so that only affects
my perception overall, not the product’s effectiveness).
I also strongly believe that every little bit helps. For example, on its own, doing the A-pillars is hardly worthwhile, but as part of an overall strategy, that fraction of a decibel adds up. To take a business example, what’s a single cherry tomato worth? But years ago, an American Airlines flight attendant suggested removing them from salads b/c people seldom ate them. The company listened and the annual savings was $100K+ (at the time, AA operated over 4,000 daily flights). She got a nice chunk of that too through the company’s IdeAAs in Action program.
