Hi there... i'm writing from italy so i'm not sure to use the correct technical terms. Basically for this first step i used
- 180 grit sandpaper
- 300 grit sandpaper
- 150 watt "square plate type" orbital sander with 4 mm poliuretane soft layer between plate and sandpaper.
- 20 minutes of work including all 5 faces (i've left unaltered the bottom)
I guess i've removed about 150-300 micron of chemical modified plastic with 180 sandpaper. Then i refined the surface with 300 sandpaper in order to hide and avoid any sign of mechanical work. Grooves and fissuration were treated succesfully using the edge that sandpaper makes surrounding poliuretane along the border of sander square plate.
Surface is now a little smoother than original but it still retains part of the original plastic texture, i guess, because of the original "particled" polymer. Next fase i already tried on a severely yellowed mac LC implies the use of a clear coat polish like the one used to remove scratches and make car shining. I still have to address the "para-serigraphy" yellowing with a lens.
My apologies for english spelling.
