Post processing
Definately it needs some post processing with dremmel for grinding or smoothing.Have in mind that the trailing edge (the rear edge where the air last meets the wing) needs to be as sharp as you can(some aerodynamic black magic here) for maximum efficiency.grind it and smooth it also for better visual results
