star wars themed tank and model kits in aquariums
Super glue cures white-ish underwater so I wouldnít use that. If it is an aquarium safe plastic it seems like it would be okay, #2, #4, and #5 plastics I know are aquarium safe, if the colored bits were painted on and not made of plastic Iím not sure though? An idea might be to have someone 3-D print a model for you using a safe plastic?
Cool idea btw.
