After UV post cure, I wet sanded (water) the coarse marks with 800 grit sandpaper
Then I moved to 1200 grit sandpaper, and continued with wetsanding
I applied blue buff (proxxon kit, fine?) with cotton tip, at low rotation setting (applied a lot of force here) DO NOT FORGET THE MASK!
Finally I sanded with the ultrafine 2000 grit sanpaper using machine oil.
I applied first layer of acyrlic finish with a brush (gloss).
