I would appreciate it if anyone could please share a recommendation for a lubricant for acrylic. I have an item where on piece of acrylic snaps into a channel cut into another piece of acrylic and would like to find an appropriate lubricant that will minimize wear and friction. I have used WD40 as an experiment and it worked fairly well for a short-term test but I don't know 1) how long it would last/provide benefit and 2) if it has any adverse affect on the acrylic (e.g. swelling, breaks down the plastic over time).
Thanks!
