Lumiseal FX is a water-based, nonyellowing, blush-resistant curing and sealing compound. The product delivers high-gloss sealing qualities that are resistant to discoloration from ultraviolet light exposure. The product bonds to previously sealed surfaces with minimum preparation and will not blush or turn white when rain or other water sources come in contact with it. This compound is formulated with advanced, premium, high-density, pure acrylic solids that don’t discolor like water-based acrylic sealer products.
