Plasti dip hides?

Hi I recently bought some large rectangle glad containers that will work perfectly for my ball python. But what should I do to make them not clear? I have some extra plasti dip from my car I was thinking about using that. Or idk spray paint? Or stickers?

I know some people use it in aquariums and frog vivariums with no apparent issue. As long as you make sure it has time to cure completely I can't see it being a problem.

Krylon Fusion spray paint is another good, safe option.
