Use a dewaxer (any of those discussed, we use Interlux) before you start sanding. Otherwise, you risk pushing the mold waxes and any other grease and grime into the fiberglass. You do want to dewax anything you are going to paint first, particularly the bilge. The boat mold had a release wax in it when the boat was built and you need to get that off the surface.
