The green Scamp is feeling blue...

Try using a clay bar. It is very important to ensure that the car, or at least the affected area has been washed first to ensure that the surface is thoroughly clean. You must also ensure that you use plenty of detailing spray or soap and water to allow the clay to glide freely over the surface and prevent it from inflicting any damage.

When claying, you should be able to feel the clay drag a little when you move it across an affected area, this is where you should gently but consistently work back and fourth over the area until the over spray is removed. The clay should be folded and re moulded to reveal a fresh contaminant free surface before moving onto a new section. Once clayed, the area should be rewashed or re rinsed and dried to remove any residue. You should then polish the area with a suitable product to ensure that it is restored back to a high standard
