Priming the cockpit sills has offered some perspective on the white priming process.

The “gloss” white primer has been a difficult aspect of the build since introduced to the project. After various thinning and application techniques, I’ve come so some realizations.

• At times, I believe I was overthinning
• MEK, lacquer thinner, and acetone all provided similar results
• Spray technique and coverage had more effect on appearance than thinning.

The largest realization was that I’ve altered the chemistry of the primer, and that plays the largest part in the difficulty I had in getting a consistent look to the primed pieces.

A lack of adequate Part-A (white) mixing allowed key components of the primer to be poured off in early batches. The primer now has a matte, or at best satin, appearance. Earlier batches had a noticeably thinner consistency.

I’m bummed, but this is where we are at now, and the look of the visible portions of the cockpit has stabilized into a bit of a consistent finish. It looks nice.

The sills came out great, bearing in mind the above, and should fit the finish of the rest of the cabin area well.
