Today I painted the rest of the wing white. By the way, the dates on these post are not the actual day of doing the work. I use the date field to keep the pages in order. But the dates are within a month or two of when I did the work. Today is January 23, 2016.
The white got two coats. The first one was medium and the second was more than medium, but I'm not sure if it was heavy. I did not get any runs. So perhaps it wasn't heavy enough. But I looked and the paint was laying down smooh and looked good right away, so I think it is fine.
I moved pretty slowly and kept the gun fairly close to the wing.
I forgot to mention, I've started wiping down the part after sanding the primer with a rag pre-soaked with isopropal alcohol and denatured water. I got them at the auto parts store. These rags seem to remove the dust better than a tack rag. Then I de-wax and de-grease, heavily before painting.
