Hi all It's me again. That fly on the cyber wall. Anyways, I'm constantly lurking around these here parts. And have learned a lot. I now have 2 plant tanks out of 5. {I'm working on the others} Here is my question. I want to paint the inside of the hoods white. Do I need to seal it or something? Or just go get a can of Rust-o-Leom and paint away?? Thanks Erik
