Hi Carlo,
Yeah, my crestron system controls the hood (simple contact closure). From what I've read, people that have formed it to the glass have had the same issue. I guess it bonds really well to acrylic though, but I didn't want to do it that way in case I decided I didn't like it. Lucky for me, the hood was closed. It still splashed some water over, but if the hood was open when it happened it would have been a mess.
