TotalBoat Gelcoat will not cure to a glossy finish. Once the gelcoat has cured, remove the PVA (polyvinyl alcohol) or mold release wax, then wet sand and buff the surface to a high-gloss finish.
Before wet sanding, gelcoat should be fully cured and dewaxed. When wet sanding, take extreme caution to only sand high points, as needed - do not sand through the gelcoat. Start with coarse sandpaper, either 220-grit or 320-grit sandpaper for rough areas, and work up to at least 1500-grit sandpaper or finer, removing deeper scratches and imperfections.
The next step is to use a rubbing compound such as TotalBoat TotalBuff, as directed, to bring out the high-gloss finish.
After the rubbing compound, using a finishing compound such as TotalBoat TotalShine, as directed, can elevate the shine to a true mirror image.
Finish by protecting the gelcoat with a high-quality wax product, such as TotalBoat Premium Boat Wax.
