Remove any hardware, whether metal, plastic or wood, from the section of the hull you intend to paint, using wrenches, screwdrivers or other tools as necessary.
Remove any pre-existing paint with a fiberglass paint stripper if your hull is painted rather than simply gelcoated. You should not have to remove the gelcoat from a new hull, as it will not have picked up the wax and contaminants that an older boat might have. Likewise, you should not face any nicks or scratches requiring repair.
Tape off the borders with any sections of the hull you do not want painted, and prime the portion you intend to paint using an appropriate fiberglass boat hull primer.
Paint the boat hull using fiberglass boat paint. You likely will need several coats. Follow that by applying fiberglass boat sealant, again applying as many coats as needed.
