Hey,
Here is a before and after,
in the first image the original clearcoat has been sanded with 600 grid
and you can still see the planking and ballmarks
after two layers of automotive 2K this is the result,
it needs another layer to fill up the insert damage, but you get the picture
the two layers are sprayed in an interval of one month to let the playfield really soak up the clearcoat, then it gets sanded and a new layer is sprayed
