Hi Mate
in my own humble OP nothing wrong with sanding lines as long as they are
in line with the boundary layer flow ;-)
You could put some dirty oil over the whole airframe, go flow for half
an hour at the best cruise speed, take pictures then sand all over with
1200 grit in those directions. You might get a few extra knots cruise
speed. (probably would imho) More or less what the glider
fundamentalists do.
