On a FB page I follow a Martin McGuire posted this shot of the weapons bay on an F-35A that is built OOB, goes on to say no AM required for this kit, even includes masking.

There’s a guy on the Scale Modelers Critique Group who has come closer than anyone I’ve seen to nailing the Have Glass finish, color and sheen on the F-35. He gives his recipe in the thread if anyone wants to check it out.
