I bought a used Pygmy Coho a little while ago. The varnish on the hull was peeling and the previous owner had sanded some of it off. It has a couple of deep scratches along the bottom, but nothing that goes through to the glass. The problem is the bow. It's missing a couple square inch chunk of wood that I think needs to be replaced. It looks to me like the original owner had initially used some sort of putty to smooth out the bow, but I'm not sure. See pictures below.
Varnish on hull
I'm pretty sure that I can remove the varnish with a random orbital sander and 120 grit paper. Then either I can paint the hull (with Brightside?) or wetsand with 220 and varnish (I've never varnished anything before).
I'm not so sure what to do about the bow. Any suggestions?
Please keep in mind that I'm a complete novice at this.
