I used acrylic paint. Takes longer and you gotta put at least 2 coats on but it's easy to remove it if you ever want to change the color from blue to black or the other way around.
I use that paint like Frank's Red Hot. Lol. Best damn rattle can paint ever.Sprayed my old 40g breeder stand with it and you'd of thought it came from a spray booth. Some people actually did ask me that. Lol.
Just mask, get matte or flat, and spray away! But remember, light thin layers, little by little. Let each passing layer dry 5-10 minutes minimum between coats. The longer the better. If you go to thin it can scrap off if something bumps it, but too thick and it will flake off also. Thought this paint seems very resistant to that.
