Make sure you have covered the whole area with the base coat and do the shading only on a previously prepared area. Use FADE OUT THINNER to blend the dust that has settled around the repaired surface and to eliminate optical gloss differences between the old lacquer and the newly applied acrylic clear coat.

Polishing and removing inclusions

Usually polishing is unnecessary as SPARK 57 VHS 2:1 gives the surface a perfect look immediately after application. If there are any impurity inclusions, it is recommended to remove them and afterwards polish with a polishing compound.
