Finish your job with a POR-15 Top Coat or any other
POR-15 coating that suits your needs. Most of them have no sensitivity to UV light. They are highly flexible, non-porous, extremely scratch and chip resistant, and strengthened by exposure to moisture.
The secret lies in POR15's curing process. Most paints dry through evaporation, but POR15 dries faster when moisture is present. It has the opposite chemistry of ordinary paints. Now add to that POR15's incredible hardness, toughness, and flexibility, and you have a coating that is practically indestructible.
