120 then 220, but maybe 400 after that. The plastic repair stuff is at the bike shops. It comes in a purple and white box and hac PC on it. I think PC is the brand.

 

I bet you could melt wax into the scratches, and then sand it when its dry. It works with snowboards, so why not quads!

 

The only thing that I don't like about sanding the plastic is that I don't want it to have a dull finish!

 

Wet sanding will take out most scratches, but you are right, Trevor, it will leave the plastic looking dull, but take some polish like 3M metal brite or such, and using a foam bonnet on a buffer ( a cloth head will create too much friction heat ) you can polish the hazy plastic back to the factory shine. then some Son of a Gun or Armor All wiped on, and it will shine better than new.
