repairing plastic lawn chairs - best method? [View all]

yes I'm cheap. also these are harder to find "big and tall" chairs. two of them cracked at the top back, not sure how - possible got the car door slammed on them when they weren't far enough in the back. anyway I have done the drill-holes-and-wire-together and the drill-holes-and-bolt both sides to a piece of wood/plastic/metal scrap. saw this how-to using super glue and baking soda. anybody ever try it? any other glue actually work? (nothing I tried before does but it has been a few years and I think there are new products out there)
