Thread: Scale repair question

Some plastics you can heat and fuse. Plastic weld. Some work better with glue. The fun is learning what it is made of and what will work. If glue holds it but it needs more strength you may be able to hot knife it on the inside. Which in short is: melting it and mixing by spreading back and forth across the crack with a knife hot enough to melt it. Just don't burn it. And try not to breath any of it while you work it :<0)
