OK now for the fun, I primed along the rivet lines of the leading edge on the inside and started to rivet the ribs in. Turned out very nice as I had hoped. While riveting some rivets I accidently dropped my bucking bar and put a little pin dent in the skin, after cursing myself I learnt to put some rags in the bottom just in case I did it again. This small dent will come out and won't be noticed once the wing is primed and sprayed, but I am still angry at myself for being slack.
