Schmutz for System Cases

[Lenshead1]

I've got a 2004 R1150R with system cases that I love! I've got some small scratches from my boot on the cases- any way to polish that out? 2nd- What kind of stuff can I put on the cases to make them look their best and keep them nice. Armor-All type stuff doesn't do well once they get wet. Meguires Back to Black (name?) is made for plastic moulding etc. but seems to get streaky. What's the best schmutz?
Thanks!

I like the stuff BMW sells called GummiPflege. It'll make your bags and all the rubber and black bits on your bike look new.

*Don't use it on your tires*
