Sanding and polishing panels

Sanding1To get rid of the spin lines that came from the manufacturing process of the aluminium dome, I started sanding with a rough 60 grit and then worked my way up from there.

Here are all the dome panels that will have a blue finish. I more or less followed CuriousMarc’s choice of grit levels. First dry sand by hand up to about 320 grit, then wet sand up to 2000 grit (very messy indeed), and finally Micromesh to take it up to 12000 grit. The aluminium still has a rather matt look but when touched it’s smoother than a baby’s bum.
