finishing rudder cap

[Mark Henderson]

What is the best way to smooth the seam in the rudder cap?. Mine has a very pronounced "v" along the seam.From what I have gathered from other posts, the resin used is polyester if the part is gelcoated. Is it better to use resin with flox or micro bubbles, or some sort of filler like bondo? If I go with the resin, do I remove all the gelcoat in the area, or just rough it?

Thanks

I would roughen up the areas and use Super Fill or epoxy and mirco balloons in a paste. Very easy to sand.

Superfil is very is extremely light bondo for airplanes.
