Refinishign Wooden Boat

[stauter99]

I have a a small wooden boat(bosarge) and it is stained on the inside with a plyurethane finish. It isnt peeling but in some spots it is scratched and need refinishing. Can I sand the poly down(not all the way to the wood) and refinish? Will it look good(It wont show scrathes from sanding etc)? I painted it but have never redone it before. The finish is 2 years old. I appreciate it.
