Abstract: A protective, sacrificial, water-reversible, coating composition for the protection of substrates comprised of water, a volatile base, a film-forming acrylic polymer in a water dispersion form, a compatabilizing polymer, specifically poly (2-ethyl-2-oxazoline), a poly acidic polymer (pH specific in terms of its solubility), wherein said coating is both water applied and water reversible or re-soluble under specific pH conditions.

Abstract: A protective water reversible clear coating composition for the protection of substrates comprised of water, a volatile base, a film-forming acrylic polymer in a water dispersion form, a second film-forming polymer, specifically poly (2-ethyl-2-oxazoline) that is miscible with the first dispersed acrylic polymer, a poly acidic material (pH specific in terms of its solubility properties), and an alkaline swellable thickener that also can be water soluble as a function of pH and wherein said coating is both water applied and water reversible or re-soluble under specific pH conditions.

Abstract: According to one embodiment of the present invention, at least one puck light with a cover and a base magnetically held together is provided. Other embodiments include a cover and a base magnetically held together while the puck light is mounted to the underside of a horizontal surface, and where the magnetic attraction between the cover and base provides for the removal of the cover from the base by hand without a tool. Other embodiments include two differently shaped covers that are interchangeably attachable to the base. Other embodiments include at least one puck light with a cover and a base magnetically held together, and where the puck light projects a shape onto a support surface and perpendicular to the support surface when the puck light is attached to the surface, where the largest dimension of the projected shape is at most four and one-quarter (4¼) inches.
