The original formula is quite frankly priceless, however for newer cars waterborne technology in coatings, xirallic and metallic composite acrylic paints are softer than the paint of yesteryear. In the retail market where paint does not discolour or fade in the same way (especially red pigmented paint) the full need to restore the original colour is not required. Despite this, scratches and swirl marks still happen (especially noticeable on black cars) and thus a cutting compound is still needed in order to remove a microscopic layer of paint.   T-Cut The Original Restorer will be available in 300ml, 500ml, 2.5 litre and 5 litre tins, almost identical to how it was six decades ago
