Re: Glue for plastic
One of the most impressive glues I've used recently was Stormsure Flexible Repair Adhesive, which is essentially a one component flexible polyurethane.
As an experiment - I had a pair of Wellingtons that must be at least 25 years old, and that had split almost completely across the full width of the sole, directly under the ball of the foot, where it bends the most - they were ready for the bin, but I tried the Stormsure product on that split, just to see what it would do; 18 months later, they're still in reguar use, and completely watertight.
As a urethane, provided the surfaces are clean, roughened, and degreased, it'll stick like the proverbial to almost anything... but it's also a flexible product, so not ideal for everything.
