All right, Here is what I found out when trying to attach 2 pc plexiglass on edge.
Acetone will not melt plexiglass at least not in my life time.
MEK will work but the working time is very short and you need to get it right the first time. Joint not as strong as I would like.
urethane is messy and looks bad also not a true glue joint it is still flexable
Sealaprene works well but also not a true glue joint and the acid resistance is questionable. It is also messy will not wipe off if you get it on the Plexi.
Winner is Weld on #4. Tried #3 dries very quickly but blushes the glass (turns it white) #4 produced a Clean clear welded joint, but takes longer to set up. I bought this at a plastic sign company, cost about 5.00. You don't use much so it goes a long ways.
