A handheld infrared light for applying wax to a surface of an equipment at atmospheric pressure is provided. The handheld infrared light includes a body defining a lighting cavity, a body width of about 3 inches to about 8 inches, and a body length of about 4 inches to about 11.5 inches. The handheld infrared light also includes at least one light positioned within the lighting cavity. The at least one light includes a bulb having a power output of about 300 watts to about 750 watts.

Devices and methods are provided for removing wax from surfaces, such as the exterior surfaces of surfboards. The devices are configured to be sufficiently stiff remove hardened wax, while being soft and pliable enough to avoid scratching or otherwise damaging the underlying surfaces, and to permit the devices to conform to contours and curves on the surfaces.

Provided are a sliding instrument having a low frictional resistance to the snow surface, the ice surface, or the water surface and having excellent sliding performance and a method for manufacturing the sliding instrument. A sliding instrument to slide on snow, ice, or water includes a sliding surface (1) to come into contact with the snow surface, the ice surface, or the water surface, and the sliding surface (1) has a surface roughness Ra of 1.0 m or less. A method for manufacturing the sliding instrument includes polishing a sliding surface (1) using a polishing composition slurry containing abrasives to make the sliding surface (1) have a surface roughness Ra of 1.0 m or less.

A process and tool for the application of wax onto watersport boards including, but not limited to, surfboards, longboards, foam top boards, skim boards, standup paddle boards, boogie boards, wake skateboards, and wake surfboards. The process includes shredding wax with the use of a handheld grating device having a cutting blade with grating holes. The process further includes distributing the grated wax fragments onto the surface of the watersport board while continuing to rub the wax over the cutting blade of the grating device and layering the grated wax fragments over areas of the board surface where grip is needed, and then gently pressing the wax fragments onto the surface of the board to create a texture for ideal grip and traction needed to stand on and control the watersport board. One or more scraper edges on the grating device allow for removal of the wax from the board surface.
