On the contrary, my experience with the Diehl wing skins was just as much if not more sanding to finish. Between my using the Diehl skins and helping others with their foam and wet lay-up wings, I would go for the scratch-build foam and wet lay-up method. It's cheaper and takes about the same time. I did get longer wings and easily installed wing tanks using the Diehl wing skins.
