Since Zinc Chromate is not "self etching" do I need to pray on some "etching" material prior to painting?

Does Zinc Chromate need to be prepped with ethching?
Etching before zinc chromate
My AI with long experience says all you need to do is go over the surface with Scotch Brite. Tried it & it seems to work well & it doesn't take long. Then degrease with acetone & spray away!
