Hi Ron:

    I too am looking for a way of coloring the CPVC pipes in my tank in
order to "tone them down", and was pleased to see your response to Roger's
question. Could you tell us what actual brand you used? I'm not a chemist by
any stretch of the imagination, but would guess that different formulations
of epoxy paint could differ in their toxicity. And what about the epoxy
paints used in marine (boating) applications? I know they are available in a
wide range of colors.
