I’m cleaning up a tank for a friend of mine and am going to paint the back. The only problem is is that there are hard water stains on the back. If I paint the back will the hard water stains mess up the paint?

It certainly might look blotchy. It might be better just to attach black foam board to the outside back panel. Its water resistant, inexpensive and easy to remove if things change.
