The rudder was sanded using 36 grit disks. There was a bad bulge on the port side. In order to true up the surface, it was necessary to actually grind down to the styrofoam (the area round the cracks in the photo). An "air file" with 36 grit paper was used to make the surface as flat as possible. Then a light weight Spectra cloth and polyester resin were applied. This will be faired with 3M filler and painted. 3M 5200 will be used to seal the rudder stock where it enters the rudder to hopefully prevent this problem in the future.
