What to use

[Roy]

To rub down the paint on plastics so I can put a new undercoat then new colour on me Diamonds????

Wet and dry sandpaper, Like a 1200 grit (that's what I used). Maybe slightly courser.

or slightly corser and then use a platic primer or etch prime to ensure a good key

good luck
