Hi Phillip, We've been making stuff with double treat for a while and haven't run into any delam trouble. You do need to watch the handling procedures - protecting the panels from bare hands. Although when it does (rarely) occur the smudges are quite apparent. On the plus side you get to skip the oxide process. Hans ~~~~~~~~ Hans M. Hinners Materials (& Process!)
