Gtechniq - Car Care Products - P1 Nano Polish - 100 ml Description P1 Nano Polish is based on the highly versatile abrasive technology, is also effective when applied by hand. This is especially useful in tight, intricate areas or on thin, small panels that are difficult or impossible to safely polish by machine. Conventional abrasive products can leave scratches and scouring behind that are then masked by polishing oils and fillers. This gives the appearance of good results when defects have actually only been temporarily filled. P1 Nano Polish removes defects without masking so the results you see are in fact the results you get.
