Just got my ball python an upgraded tank, but before I put her in it I want to black out the sides so she can feel more secure. I used paper and hot glue last time, but want something a little cleaner looking for this larger enclosure. And before anyone asks, this will be going outside the enclosure. Not inside.

So I'm just curious if anyone knows any good, safe brands of black spray paint to use? Any that might have been used before successfully? Even brands that would be good to avoid entirely. I'd also be interested if someone knows another technique that might work and still give a clean look that paper and hot glue just can't provide.
