Sailplane Refinish Video 4 - Paint & Primer

Video 4 in the Sailplane Refinish series adds paint and primer to the Rolladen-Schneider LS-3a. In past videos, we repaired a wing flap, sanded off old gel-coat, and applied a veil cloth where needed.

I was "involved" in sanding off the old gel coat from an ASK21 (recently). I spent, about, 3 hours, sanding about 1 sqft of gel coat. A won't volunteer to do that again. I'd rather pay the folks at Wings and Wheels to do it. It looks like they did a better job than we did.

Its a really nice series, but I hoped for for a bit more details...

Hi Gents. A glider is not a car. You are not allowed to apply thick layers of Bondo on it. It is easy to apply new thin glasslayers and make it smooth but the empty mass of the glider increases, and the center of gravity goes backward. If you ask to do such a job assuring zero mass-increase NO sailplane refinisher will EVER give you a quote or touch your plane. If you get a quote with assured 2 kg's limited mass increase you have the best sailplane finisher in the world.

Bondo was not used or thick layers of any filler. A little weight was gained in the end, but not much. As we all do when getting older ;)

How do you ensure that the profile on the wingtip stays the same?
