Cluster Screen Polish

Sand the whole thing to remove the scratches, using fine wet and dry. First try 2000 grit if that doesn't work (it will work but take time!) drop the grit down and then back up to finish - use it wet too

As for polish, Meg's do a plastic restorer, Cerium Oxide works... Have even used AG SRP in the past!

You can polish it by hand or use a small foam or felt polishing pad in a cordless drill - just use it slowly and keep the plastic cool

Swiss vax mechanical repair is quite good as it has abrasive and filling properties.. agree for polish have used meguiars headlight repair successfully in the past too.

A before and after on my mates headlight using wet & dry (sanding wet) and Auto Glym Super Resin Polish on a soft black foam pad in a cordless drill
