We all know an alclad surface is naturally corrosion resistant. To some of us that can mean "no primer required". My question pertains to those kit parts that do not have the (usually blue) vinyl coating on them to protect their alclad surfaces from scratches etc. Specifically, my question pertains to wing ribs which we must straighten and flute. It is my understanding these parts after being stamped out in a press, are heat treated. True? If so, do these parts still possess a 100% pure alclad coating?
