You may have a tang inside rusting and forcing the surface outwards. Rust expands.

Grind it open and investigate. I would do this at the end of the season in case it needs a rebuild.
Do you mean just take off the skin or talking about the core itself? Also if I grind fill what do I fill with? Some type of epoxy or just fiberglass resin? How do I go about smoothing it out? Sorry for the basic questions but once I get past them I should be alright. I think I will paint and sail and dig into it in 7 or so months. Also, is it possible to do this without taking the rudder off?
