Rustoleum for Terrarium, is it safe to use?

[lemon-zing-tea]

Hi! I know it's not aquarium related, but I thought those on here would have the most experience. I'm modifying a lantern into a home for a praying mantis, and the lantern itself is iron but painted. I'm not sure if the paint would be toxic when wet (from misting) or if itd rust, so i was wondering what i could use thatd be pet safe to seal it. I know of clear coat rustoleum and krylon fusion, but instead of spending money I thought I'd ask if something I already have is safe to use. Here's a picture of it (please let me know if you cant view it). It's called Rustoleum Gloss Protective Enamel, and it does have a color (beige), not clear. So after spraying and waiting a few weeks+rinsing when dry, would this product be ok to use as well? Thanks!

They reccomeded to me not to use it underwater. Id suspect its okay when dry in aterrium

So it won’t be underwater, but the inside of the terrarium (where I would be spraying the sealant) would be very humid from regular mistings and water droplets would come into contact with it
