So...we have a couple of sliding glass exterior doors. In the dining room, instead of drapes, we have flat vertical slats of plastic, which I suspect to be Styrene. They work sort of like "Mini-Blinds", but vertical, with flat slats, and plastic instead of metal. The connections at the top of the slats fail, specifically the slots stamped into the top of each slat breaks out the top, and the slat falls to the floor.
My fix was to buy a sheet of 1/16" K&S Styrene at the LHS (well, not all that local), cutting strips .250" wide and gluing them full width across the top of the slats, bridging the broken out slot that the slats were supposed to hang by. I cleaned the gluing surfaces with Naptha and used Plastic Model glue "for Styrene". It worked great, but it also didn't hold very long, 2-4 weeks at most. The glue joint failed, one at a time, two of six total so far.
Looks like I need either better prep or better glue. What say you wizards of glue? Don't make me bolt this crap together with 0-80 machine screws!
