Blasted frames actually take off material or smooth down the surface. Duracote and Ceracote add to the frame but not so much as to change the thickness of the lens orbital channel. Even when I do copper, chrome, or brass plating it adds a bit more to the frame but the lens orbital is wax covered so the plating does not get in there. @THE X-MAN should be able to chime in on this also for a bit more clarification.
Your pretty much spot on,except i think blasting really only changes the texture of the surface and doesnt remove material,at least on these frames anyways.
Its even worst if it remove/take off material off the frame, that will mean all cuts will be deemed smaller than the stock frame? But if @THE X-MAN says it doesn't I trust him on it.
