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

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!

Sounds good. I actually did that on the exterior of my -6 and it worked really well, but I was never sure if I was actually following the 'rules'.
