Put the sandpaper on a flat surface and run over it with the flange in figure 8 patterns to avoid high spots. The smoother and flatter it is, the less force needed to seal it up.

Grinders are about a week 40grit i think.

I’m using 5 Star silicone gaskets with the lips trimmed off each side and they hold a pressure test with the air compressor by sticking the dusting gun up the end and taping it in before pumping the whole still and boiler up and spraying soapy water on the joints.
