Jeff, I will do my best to get this info to you. The blockout glass topic was in a casual conversation last summer so I hope I can find the guy. Since Dave at Tecnolux is on our list I take it he would have mentioned if they stock? Will get back to you on list Monday or Tuesday, even if I strike out,OK? I enjoy the info on this list it is really helpful when you are trying to be serious about learning this trade. Thanks. Best regards, Don
