EPO rudder refinishing
By Dave Raughley
I just refinished my EPO's last summer and they came out beautiful.
I used West System epoxy with their graphite filler and coloidal silica
filler both. the coloidal gives the epoxy a thicker consistancy, so you get
some build up and it makes the epoxy harder. The graphite filler does a
couple of things, (1) it gives the epoxy a very very dark grey color, it's
almost black, (2) It gives the epoxy a great U.V. resistance, (3) since
graphite is a lubricant it reduces friction on the surface. I sanded my
rudders lightly with 320 grit sand paper then applied the epoxy mixture with
a small disposable foam type paint roller. I applied three light coats,
sanding between each coat, three coats was enough to cover the other repairs
I had made to the rudders. After the third coat I wet sanded, with an orital
finishing sander, starting with 320 paper and working up to 2000Grit wet
paper. At this point they shined, so I polished them with a teflon polish,
just to finish them out. They have held up very nicely.
