I decided to go with .020" 6061-T6 aluminum for my stabilizer skin, and I believe I made the right choice. The material is still in excellent shape after all the steps necessary to get it on the workbench, measured, scored and cut. I then followed the ZAC plans precisely to precisely bend a very nice looking stabilizer skin. The Zenith skin is only .016" thick (cheaper material) and sells for $114. The only difference is that the holes are pre-drilled. I paid $68 for a 4 x 8 sheet of .20" aluminum, and still have some left for other parts.
A very straight and gentle bend
Testing to see how the skeleton will look inside the skin. Very cool to see things take dimension.
