Greetings,
I had a quick question on which glue you guys recommend to glue strong magnets to plastic like PETG or Polycarb? Im trying to glue the magnet to my spider-man lenses. Hot glue seems to be most common, but I have had no luck with hot glue. I do have a good hot glue gun and quality glue sticks. I tried to go as hot as it can go without warping the thin plastic lenses but still comes off after a while. I have tried JB weld which is my go-to when all else fails, but since JB weld has metal particles in it, i think the magnet effect the strength as it also comes off after putting on and takeing off my lenses. I would buy two part epoxy but i want to make sure to get one that works so im not buying many different ones with trial and error.
 
PETG really likes acrylic adhesives like Devcon plastic welder. But an epoxy will work well, too. Best to thoroughly scuff up both the magnet and the plastic first.
