I prefer Behr brand interior latex. Goes on evenly, cleans up easily, mistakes can be corrected, doesn't smell up the house, and it can be removed and color changed if desired. I tape off the plastic edges and use a 3" smooth roller; usually apply 3-4 thin coats to cover thoroughly. Glass must be clean whatever paint you use. Royal blue and black are my preferences, and the blue is more forgiving when the water is not crystal-clear.
