Hi, everyone, I have a one of those see through resin toilet seat that look like they have fish & shells in them. I love it but Have had problems with it for ages moving about and having to tighten hinges, have to do this every few weeks/months. Finally hinges broke and I bought replacement hinges but it looks like the hole where the hinge screws go in is chipped(OH tried to fix it but he isn't great with DIY and can resort to brute strength!)I don't really want to buy a new one unless I really have to as money is tight, I am sure there must be some sort of glue for plastic/resin that can fix the screws in. Any advice please?
