I tried the rustolium and one other brand from home depot. Neither one of them worked. I fell for one of those pinterest glow in the dark pot posts and just had to have one. I even primed the pots first with white, and then did 3 layers. I will say that the rustolium slightly worked, but only very faintly and on the outer rim of the pot only, and it faded very quickly once the Sun was down. If anyone finds anything, please let us all know!
