Yellow cutting sponge M14
The yellow cutting sponge has a hard density and is ideal when aggressive compounding/cutting is required
The yellow sponge is used when severe paint correction is required. The cutting process is aggressive and may leave micro-marring on the surface that needs to be removed with a medium/firm-density sponge
A polishing compound rubbed against a painted surface acts like an abrasive and removes microscopic layers of paint to even out the surface. It is this process that removes the appearance of dullness and scratches
Automotive paints generally have 3 layers:
The clear coat is the layer on the car that will be polished and is extremely thin - about half the thickness of a piece of paper. It is possible to remove scratch marks if you can&t feel them with your fingernail. Scratches deeper than the clearcoat won&t be corrected by polishing
It is highly recommended to invest in a paint thickness gauge to measure the thickness of the clearcoat. The polishing process should never remove the clearcoat
