Well, it's all white now, with two coats seeming to be enough.
I did manage one run in the white -- fortunately it's on the bottom of the plane, so depending on how bad it is I may not even bother to try sanding it out. I did try to take a picture of the run, but trying to photograph a run in white paint is not an easy thing.
I thought I'd show my backwoods painting fixture. 1/2" square aluminum, surplus from a job long ago, with a plate bolted onto it that goes into the motor mount holes -- all typical there.
The special "I live in the sticks" part is the vice grips. The one on the aluminum square is so I can handle the plane one-handed, without touching the paint. The one on the sawhorse actually holds things in place while I'm painting.
I can rotate the plane on it's long axis any amount I want, as long as it's increments of 90 degrees.
So far I haven't dropped a wet plane into the dirt, so, fingers crossed.
