Mike, I have the numbers for the left wing below. The weights do not include flap and aileron, however. I did not record weights of the right wing. I assume they are similar.
1) Left wing monokote covered but less flap & aileron was 393 grams.
2) Left wing fiberglass covered, primer, two color-coats epoxy paint (also less flap & aileron) was 420 grams.
This gives a final weight gain of 27 grams, an increase of 6.9%.
Overall, I'm quite happy with the outcome. A lot of work was involved in the finishing. Lots of sanding after glassing, and yet more sanding between primer and color coats.
