Hey all. So, I’ve been trying to paint the back of one of my aquariums and for some reason it doesn’t seem to want to take. It’s a glass aquarium. I’m using acrylic paint with a foam roller and it’s just odd that after two coats (it was dry to the touch) it looks like the tank wants nothing to do with it. I used to be a house painter for about 6 years so I know my way around paint. Anyone have any ideas? Glass was thoroughly cleaned and dry prior to application. Thanks.
