I collected the fuselage from being sandblasted and primed today. The company I used is called AirBlast and work out of a disused airfield at Gosfield. They were recommended because they have experience with the sort of thin wall tubing used in aircraft - too much enthusiasm with the grit gun can blow holes in thin tubing!
The airframe now looks smart and clean in it's coat of white epoxy primer and will temporarily be stored in the hangar at the airfield where my LAA inspector is chief engineer.
