Total guess here- These formed tops remind me of the type of Kevlar, Nomex and fiberglass honeycomb panels used in the manufacture of aircraft. The panels are formed by vacuum or hot press. Kevlar and Nomex are used to limit fire /smoke spread.Just picked up my Black Diamond Saturday. Noticed "scales" (is that what we're calling it??) on the top of my MIC roof when I removed it. Wasn't this the other appearance problem that led to the recall?

The panels I have seen have the finished coatings applied prior to the forming process.
These edges really need to have a UV resistant strip.
