The Norton Ice foam backed discs have been designed in super fine grits of P1500, P2000 & P3000. This allows a super fine finish to be achieved after using the ceramic film discs making them ideal for polishing out even faster on spot repair applications. The new ‘open mesh’ backing technology absorbs water and moulds to the surface for equal pressure distribution. They are a beautiful wet sanding disc that doesn’t clog anywhere near as much as other brands on the market .
