I put 4 hours in this weekend on the VS/Rudder final sanding. It takes about as long as everyone complains about on their sites.. ;-) I started with some light weight fiberglass along the seem between the metal and the fairing (which also covered up the pop rivets nicely)to hopefully add strength and reduce any possibility of cracks in the final paint along the seam. Then mixed the West Marine System epoxy with microlight filler to start building up the low spots. Sanded, then build up the low spots again.. The pic is the filler in place after the second time I added filler. I think in this case 3rd time will be a charm. After this gets sanded down I should be just about wrapped up. I will wait on the Elevators and HS until I hit a slow spot on the wing project.
