The final rough sanding has been completed in the first picture and I am about to apply a filler primer.  Filler primer has some body to it and it will fill in any sanding scratches etc.

You then sand the filler primmer with fine sand paper. I gave it two coats and the result is the last picture. It is very smooth and makes a smooth transition to the skin.

I took the canopy off at this point and it is now sitting off to the side and won’t go back on for awhile.
