Why are there several overlapping coats of paint that are peeling off? I thought this was the new and flashy Boeing plane? The airline was Scoot.

    When working with windmil blades we used to call it a gel coat and the reason it gets replaced often is if water gets under the gelcoat the composite would delaminate, which is very very bad. This was of prime importance for blades that ended up in the sea or near sea air.

      Absolutely on the delamination. Paint on metal can go for a minute and be okay as long as there’s primer still protecting the metal; but on composite the flaking will just lead to more flaking. Plus, the water intrusion damage and wicking you can get with carbon fiber. Gotta check that stuff often.
