I spray it. Mask everything and turn upside down. I used Kilz spray paint from Walmart for the back (turns a nice lt/med blue). I used the pebble textured paint for the bottom. I backed it all with black so it is solid (cant see through it at all). I dont see a need to paint the sides because i like to see them better. Unmask everything, clean any over spray, clean out the inside real good just in case and you are ready to go. This is how my 75g Bow Front turned out. I also went with some live plants, driftwood and some moss. I'm pretty happy with the outcome. I plan to do my 85g next exactly like this one. I also have my breeder tank the same way.
