Luber Synthetic Lubricant & Detailer is a high-lubricity lubricant specially formulated to increase lubricity and reduce friction. Luber lubricates paint delivering a slick, non-stick surface that is perfect for using any clay bar or clay block. Luber easily lubricates the surface so that a clay bar or clay block is easily and gently glided across to easily remove rail dust, water spots, tar, bugs and paint over-spray from automotive paint and glass surfaces. Luber contains highly reflective shining agents that form an ultra-thin protective coat that allows the clay block or clay bar to work more effectively and evenly on recently waxed or sealed surfaces. Luber is synthetic which means it works exceptionally well on any surface including glass. Clay lubricant is essential to the performance and safety of clay. It provides the necessary slick surface for clay to glide on. Using low quality clay lubes or cheap detail sprays will deteriorate your bar and lead to poor clay bar performance. Also beware of soapy water as a clay lube, detergent or surfactant based soaps will cause the clay to deteriorate. Chemical Guys Luber is formulated specifically for streak free surface perfection in the sun or the shade and uniquely formulated to work with the chemical composite of clay bars. Chemical Guys Synthetic Clay+ Detailer will extend the life of your clay while delivering superior surface lubricity during claying. Clay bars absolutely need some kind of lubricant to work correctly. Without lubricant clay bars cannot move freely over the surface and work as intended. Without proper lubrication a clay bar will catch on contaminants, pull them across the surface and possibly scratch or mar paint. Lubricants aid the clay bar in lifting particles and allow the clay bar to move freely from raking roughly across the paint and causing possible scratches. Lubricants are formulated to work with the clay bar and will not impact the integrity and cleaning ability of a clay bar. Shampoos and car wash soaps may damage the clay bar leading to deterioration, which in turn will limits its cleaning ability and shorten its life span. Specially formulated clay lubricants are formulated with uniquely engineered surface lubricants to allow for superior gliding of the clay bar and provide a slippery protective layer that clay bars can safely glide across. Many things can contaminate your vehicle's surface including brake dust, industrial fallout and rail dust. Industrial fallout is another word for pollution, it is a by-product of our surroundings. It comes from industrial businesses and factories as well as diesel vehicles and even airplane fallout. Rail dust is produced from the friction of train wheels against railroad tracks. Over 75% of all new vehicles are shipped by rail which means nearly all vehicles are contaminated as soon as they leave the factory. Luber Synthetic Lubricant & Detailer used with a clay bar well remove these contaminates from your vehicle's paint and keep it clean and smooth.
