Short post for what seems like an eternity of sanding today. Started with sanding the primer on the canard.
As expected, there were a few places that spot putty was required. However, many fewer places than the wings. I attribute that to the hours spent on the contour of the canard.
Then I went to the left wing. I spent no less than 4 hours sanding the whole top surface. I was going slow because I though that this coat of primer would be the final coat, so I was careful. As luck would have it, with the exception of about 4 square inches of touch up priming, the left wing is done. It will be in it’s airworthy primer tomorrow. Win.
Here is where haste got the better of me. I wanted to make up for missing my goal yesterday and wanted to get 3 coats of primer on the canard and all of the control surfaces. So I washed, rinsed and let dry.
The first coat of primer went as expected. With the wings, by the time I got back around to the other wing, the primer was dry enough to do coat number two. It wasn’t the case with the canard and control surfaces.
It was a mess. The previous round started pulling up a bit. So I tried a heavier coat. That seemed to work. So I proceeded on all surfaces to be primed. But when I got done I realized that this was a mistake.
The premature second coat amplified the texture that the roller left, plus left runs. Great! To add insult to injury, priming at night is a magnet for bugs. They love the bright white surface. Well at least at this point I learned my lesson and called it a night.
Good thing primer sands like a dream compared to everything else. A bit of sanding in the morning and I can prime again. Nothing is ruined, but I did waste some time and material. The stated purpose, from the FAA, for experimental airplanes is, after all, education, right?!?!?!
