On a very light colred car, such as silver, beige, or white, the Klasse SG (layered) may reduce/remove to the visible eye light swirling. Same applied to Z5 in the Zaino line of products. Layering is the key in which these two products cover them up for an extend period of time. Much longer than 3M Imperial Hand Glaze. These two protectants should reduce the light swirls for a few months, which 3M IHG a week or a car wash.
DO NOT expect miracles though, preperation is key, use your 3M line of products to remove most if not all the swirls first. Then the few ramaining ones could be covered up with Klasse Sg or Zaino Z5. These are VERY light ones.
Hope this helps
