I've used it many many times on the outside of tanks as a background color, and it was amazing, dosn't chip, peel, flake or anything. Also goes on really easy and dries fast.
I used it on an all-in-one nano tank this time. I have a partitioned section with baffles and return pump etc. It was clear acrylic, so I painted it all black. Only time will tell if it is any good. I can imagine that rocks and stuff will scratch it off easily. But hey, right now it looks killer lol.
