Some more on faring and long boarding….
I shaped the bog with the air in-line sander. Then took a shop pencil and scribbled all over the boat. It looks like I parked in New York City next to the subway. (If I was painting I'd shoot two different color primers to show me "layers" for sanding for highs and lows.) Then I start my long boarding. Some low spots are obvious as the shinny dimples, or slight as the scribbles left on the boat. In know some chemist will correct me but basically graphite and carbon are close enough to the same whereas I can bog over it and it does not matter. Then I start the process all over again. At some point I see all the scratches and dust are even on the surface and will be able to feel the farness with my hand. Personally I can feel surfaces better then sight when checking for farness, especially if there are color variances, but that’s me. Also is a pic of a roll of sanding paper for a in-line air sander 80 grit.
