The completed airfoil practice kit. I tried using the self etching primer on the inside surfaces and mating surfaces while leaving the outside bare aluminum.

   

   

I learned a number of good leasons doing this kit, the first is how not to do a leading edge (I left way too many dents in the rounded over section of the skins from not using the hand seamer correctly). I did learn how to drill out rivets, both solid and pop types.
