I bought some small plastic pipe made for use in sinks for an airsoft barrel and since it is not pvc I had to glue it with epoxy. I tried to glue it so that the pipe would go through an end cap but the epoxy won't hold it together
. I sanded the pipe and and tried it again bot it still couldnt stick. I looked at the label and the pipe wasnt made out of the type of plastic that epoxy doesnt stick to. I can't figure it out.
