EkoPrime Questions

Hello,

I just finished priming one wing (all metal) for my Aeronca Sedan and have some questions. I sprayed the EkoPrime diluted with 10% water by volume. It was sprayed with a Tekna gun with a 1.3 tip and a HE10 cap. Temp was 75 Degrees and humidity was 45-50%. I ended up with a finish that is about like 150 grit sand paper. I have very dry air to the gun via a membrane water separator. I did have a problem applying a fog coat that was tacky. It seemed to dry on the surface almost instantly.

As I have another wing to paint, and in the future another airplane, I would like to produce a finish that needs less sanding. I suspect that I need to open the fluid needle some more to get more primer, and thus a wetter film, on the surface that can flow out smoother. Any thoughts on this would be helpful.

Also, using a red scotch bite pad gets a reasonably smooth surface, maybe like 800 or 100 grit paper. Using 320 sandpaper produces a very smooth surface but also makes bare any rivet heads that I accidentally hit with it. How smooth of a finish do I need? What is the best way to touch up any rivet heads that had the primer sanded through? Can EkoPrime be dabbed onto them?

I posted this here rather than call as I figured others may have the same questions.

Thanks in advance,

John Poulter
