I had decided to use zinc chromate (brush on, not spray) for corrosion protection on my CH 701. I went to buy it at Aircraft Spruce (PTI SPECIALTY PAINTS<br>ZINC CHROMATE PRIMER from Aircraft Spruce), and somewhat to my surprise discovered that there's two versions, "yellow" and "green." The yellow is what I used on my rudder... what's the green stuff? Any reason to favor one over the other? The prices are a bit weird, but the green is $6 cheaper for the quantity I'd buy, and hey, that's $6! Unless someone says "they work exactly the same, don't worry about it," I'll probably go with the stuff I know just to play it safe.
