I'm lucky. I had the idea of taking wet sanding sponges to the still curing primer and it took almost all of the imperfections out in no time :) This meant that I could CAREFULLY install the control surfaces and officially say that the left wing is READY TO FLY!
2 wings in primer and done. The aileron on this wing weighs 7lbs 5oz which again is a little chubby however it balances well within limits.
