I started silking the wing, this is only my second silk job so I'll probably have some mistakes. These are some pictures of my wing as I silk it, the darker finish is just low light, it really looks like the pictures where it is white. This is the Nitrate coats, 2 coats brushed on so far. I fly with the great designer/builder Dick Sarpolus, so I'm going to take the wing to the field today and get his opinion if it needs more nitrate or if now I can go onto the Butyrate coats, I'm down to 4oz. of Nitrate but I've got gallons of Butyrate. It's my understanding that the Nitrate is the glue and primer, the Butyrate is the paint.
