Regarding the carbon finish areas: Given he's probably using 200 grams/m2 carbon, which hand laid would result in a 50/50 resin to carbon ratio, giving roughly 400grams/m2, and probably 1/3 of that is being sanded off, that results in 266 grams/m2 to get that finish rather than microballoons for areas that are being painted, which probably comes to about 25 g/m2. So, assuming he's got roughly 6m2 of shiny carbon finish, you're looking at a weight penalty of about 1.5KG over the whole aeroplane. Given the size of it, I think it's weight well spent. Even if it's 12 square metres of carbon finish, that's still only 3kg on an aeroplane that looks like it will easily lift 2 tons.
