The present invention is directed to a low VOC ultra high solids thermosetting coating composition. A polymeric component of the composition includes a low molecular weight polymer polymerized from a monomer mixture containing less than 45 percent by weight of at least one active hydrogen containing monomer. The polymerization takes place in the presence of a reactive diluent. By including the reactive diluent in the polymeric component of the composition, the amount of solvent used in the composition can be substantially reduced, while still providing a pot mix of the composition with a viscosity sufficient to permit efficient coating application. The coatings from the composition are durable; glossy; impact and solvent resistant; and adherent to a wide variety of substrates, such as automobile bumpers, road surfaces and office equipment. The surface of these coatings when subjected to scuffing or surface marring action can be substantially restored to its original condition by simply buffing or polishing the marred or scuffed surface. The invention is also directed to include a combination of chemicals in the thermosetting composition containing an isocyanate cross linking component. Such a combination simultaneously increases the pot life of the pot mix while decreasing the drying time of a coating from the pot mix at ambient temperature over a wide variety of substrate surfaces.

A door is constructed with a separate member joined to the door edge by a tongue-and-groove coupling and screws so as to be readily removable and replaceable. The separate member sustains the impacts imparted to the door by carts or wagons pushed past the door and can be readily replaced when damaged, thus avoiding replacement of the entire door. A flexible cover snaps over the outer surface of the separate member to add impact resistance and aesthetic appeal. Intumescent strips may be inserted inside or outside of the cover to enhance sealing between the door, and at the adjacent door or door frame, thereby improving the fire resistance rating of the door. Accent strips or reveals of contrasting or complementary colors may be incorporated to add to the aesthetic appeal of the door. The door construction is of particular utility in schools, health care facilities and other institutions.

A buffing head (34) includes a rotary element (36) for retaining an optical disc (20) and causing the disc (20) to rotate at a first speed. A buffing element (38) contacts a work surface (30) of the optical disc (20), and rotation of the disc (20) enables corresponding movement of the buffing element (38). A restrictor (40), in communication with the buffing element (38), restricts movement of the buffing element (38) so that the buffing element (38) moves at a second speed to recondition the work surface (30), the second speed being slower than the first speed. The buffing head (34) further includes a well (86) surrounding the buffing element (38) and containing a fluid (88). Movement of the buffing element (38) causes the buffing element (38) to be immersed into the fluid (88) and to be returned into contact with the work surface (30).
