John, I looked at a number of this type of anodizing agent and the common denominator was: "After precleaning with BONDERITE C-IC 33 AERO, rinse with water. Apply without dilution by brushing or swabbing with sponge. Rinse with water and surface is ready for paint. This is a visible coating which leaves the surface with a golden coloration. The alodized surface provides protection against weather and firmly bonds paint." They all sound like primers. The "golden coloration" isn't what I'm looking for either.
