Ditto on the NuFinish. Works like a champ.

A couple other questions:

1. Do you guys stick to the same routine (grades of sanding, buffing, polishing) when preparing daggerboards and rudders?

2. On my new boat, I've hand buffed and polished it - but have not done any sanding/heavy duty buffing. The finish seems to be nice. When should one consider a complete makeover? Depends on the wear and tear, I'd assume.
