Regular exposure to sun, moisture, and salt can wear down a boat’s finish over an extended period of time. 303 Marine Graphene Nano Spray Coating provides up to 12 months of protection to combat these harsh effects of marine climates.
The specialized graphene oxide formula bonds to a boat’s exterior surface, leaving a powerful shield on the top layer. In addition to safeguarding the exterior surface, the spray also adds a deep, mirror-like finish to make it appear sleek and glossy. More importantly, the spray enhances the look of any unique properties on your boat’s surface. For example, if you have metallic flakes in your boat’s gel coat, 303 Marine Graphene Nano Spray Coating will really bring out that shine.
If you are concerned about water spots showing up in boats gel coat or glass, worry no more! With the combined properties of hydrophobic protection and surface temperature reduction, hard water spots will be a thing of the past. The dynamic graphene oxide formula contained in 303 Marine Graphene Nano Spray Coating reduces the surface temperature of paint. Doing so ensures that water cannot dry and embed itself into the surface, causing hard water spots. Any water spots that show up will be on top of the coating. Any instances of lingering water droplets are easily wiped away with a microfiber towel or detailer.
