Nothing much doing over the holiday week but deburring and dimpling tank parts – skins, ribs and baffles. Not too exciting, except for one issue. After reading some VAF posts about cracking dimples, I examined some of the tank skin dimples with a 10x jewelers loop and saw what looked like some tiny cracks on four or five dimples. Somewhat concerned, I emailed Van’s. Their response was that a lot of things on the airplane woudn’t look very pretty when magnified ten times, and that if there were no cracks visibile to the naked eye – which none were – then everything was probably ok. I decided to go with their recommendation.

Any surface that gets Proseal must be scuffed to improve adhesion, so I did just that. Here’s one of the skins scuffed with a maroon scotchbrite pad.
