WoW! What a great picture of weave exposure. Would suggest that you submit this to the 600 and 610 groups for inclusion in those documents. I was going to suggest that you can run a water soluble pen over suspected areas and if the glass is exposed the weave will wick up the ink and when you wipe it off with a tissue the result will be little colored spots. If it is merely texture there will be no spots. Did you notice this conditon prior to assembly? Susan Mansilla Robisan Lab
