I used an air-powered wet sander for fuse refinishing following gelcoat
application ... it helps. Filling and cleaning up the damage to
properly paint (regardless of the paint type) is always the most
important and time consuming part of the job. I don't know how you get
around this ... other then protecting the fuse with tape as suggested
to prevent the dings in the first place.
