CLEANING FADED OR OXIDIZED FIBERGLASS
There really isn't any secret to cleaning faded or dull fiberglass; you just need some elbow grease and something to remove
the oxidation. The application varies for different products, but in general, you need to rub the surface with the oxidation
remover or polishing compound to remove the oxidized layer. You then let the product dry to a haze and buff it off to
reveal the clean (but not necessarily shiny) surface.
If your boat isn't shiny at this point, it's because the clean gelcoat surface is pitted and is dissipating the light instead of
reflecting it. By filling in the microscopic pits, you can restore the shine. To prove this, just apply some water to the surface
and see if it becomes shiny. If so, you then need to apply something which will fill in the pores and maintain the shine.
To use oxidation remover, first wet the gelcoat surface and apply the oxidation remover using a white Scotch-brite pad or
sponge. Rub the surface either until you see color in the pad or sponge (indicating you've rubbed off all the oxidation and
are now into the colored gelcoat), or until the surface no longer feels rough. At this point, you simply rinse off the surface
and wash away the oxidation residue.
