So I picked up a Creature from the Black Lagoon gravewalker prop with the intention of putting it into my tank. Obviously I need to seal it in some way to keep it safe for my fish. The creature is made primarily out of hardened foam and then painted. What would you guys recommend to seal it? I've always heard Krylon Fusion was good but I can't seem to find standard Krylon Fusion clear anymore. I've looked into Polygem clear epoxy coating, plastidip clear and even Flex Seal liquid clear, but I don't have firsthand experience with any of them. I don't want to screw up the creature since it wasn't cheap and obviously I don't want to kill my fish either.
