Hello
Can you explain the principles behind how to get a high gloss finish on the GC3 (Glasscast 3)
After I have sanded down my surface moving down to sandpaper 2000 the surface is very Dull/matt then what do I do ?
I am thinking I then polish using topfinish 2 and hard then medium then soft polishing pads,is this correct ??

Thanks
David

You can start with the NW1 polish from around 1500 grit then finish off with the TopFinish 2 for the final high gloss finish.
