I'm wondering if there's a practical method of recognizing what kind of plastic a given thing is made of. This is a recurring issue I face when trying to fix/glue/work-with plastic stuff around the house.
More specifically, I was trying to fix the connection of a garden hose reel. I thought that the black, carbon-like, hard plastic was ABS and used some ABS-compatible glue, but the bonding came off almost immediately after put under pressure. So, before I try again, I'd like a way to identify the material and use the right kind of products for it.
