I asked the Velocity production people about their wing construction and
hard-shelling. These guys make wings for a living and have done it
hundreds of times. Do they use the wet application or hard-shell?
The answer is that it depends on temperature, humidity, and time of day.
When temperatures are rising, especially with higher humidity, the micro
slurry will out-gas and leave bubbles of delamination, so they may hard
shell instead. Normally they prefer the faster wet application as John
There is no appreciable difference in final weight, the same amount of
slurry is applied, and, since this is NOT applied to correct surface
irregularities, not much of it is sanded off, just roughen the surface.
