Prima Glide is specially formulated to work with all detailing clay. Together, Prima Glide and detailing clay create a smooth paint finish by removing contaminants from the surface. Prima Glide creates a very fine, yet essential, layer between clay and the paint. This layer is critical in order for detailing clay to slide across the paint, allowing the removal of contaminants yet preventing harm to the paint itself. Prima Glide and detailing clay are safe on glass, fiberglass, chrome, plastics and all paint types.
