Resin Black

Someone has good results with the black resin (GPB K03) I have not used this resin yet and wanted to know if anyone has good results with this resin.

The finish I get from the new matte finish resin is terrible. It is heavily textured, fills in holes and requires quite a bit of post print processing (sanding and filing) to get a have decent finish. I started with a new resin tank as recommended and did not mix with any of the older version. When I compare new prints to identical parts printed in the previous versions of black, I hope Formlabs either reformulates the K03 version or goes back to the non-matte version. Better yet, offer the older version again as well.
