Aquarium Safe Sealant?? (for Decorations)

My friend gave me the most beautiful sculpture to go in my fish tank. I'm pretty sure it's a resin. I've heard that resin by itself is safe, but the paint used on them isn't always safe.
I was wondering:
Is this aquarium safe?
Is there a sealant I can use on it to make it safe? Some people have said "use Krylon," but since Krylon is just a brand, that isn't in the least helpful. Aside from paint, they have so many different sealants that I wouldn't even know where to start.

 

Krylon fusion spray paint. I had them bake a finish at the ceramics place we used to have by me.

Wait, you sprayed it and then had them bake the object??

 

No. Sorry I should of made it clearer. You can either spray paint it or depending what it is it can be glazed.

Ah, okay.

I've also heard about getting epoxy resin from paint and body shops. Does that work?

 

Most epoxy resin or paint is ok. Its a 2 part product that needs mixed before use. If you have a paint gun it can be sprayed on and if not it has to be brushed on. I think that's the reason most use the spray paint. Its simpler to use.

Makes sense. So what isn't about spray paint that makes it safe? Sorry, I just really wanna know what I'm looking for and what I'm doing before I spray something with a bottle of smelly chemicals and stick it in my tank. Lol

 

I'm not a chemist so I have no idea. I don't think all spray paints are aquarium safe. I guess its like soap. Not all are considered aquarium safe but dawn blue is.
