Super K ?

I'm just getting started on a 14 after a number of plastic airplanes. I've been using PPG Super Koropon on all the aluminum and steel parts on the composite planes, and after 30+ years there's no corrosion on anything I can inspect. I know how to work with Super K but find very little information on RV use of it on VAF. I use an old Binks #15 siphon cup gun and keep the mixed primer in the refrigerator to extend the pot life.

I have used both 515-K011 (green) and 515-700 (light green) over the years and find no differences. Here is a link to PPG's data sheet on Super K

Any guidance from the experienced metal airplane builders here?
