I had this problem with my SS and now its on my WS6. I used the california wiper blade, i accidently rubbed the plastic handle on my hood now i have a very light streek on it. I really want to get it off, i tried waxing it, that didnt work. THey said its made of abs plastic, i think i emailed the people who make it and they said they never had that problem. Does anyone know of any way i can get rid of this mark, any suggestions would help.

 

I would try some Turtle Wax Polishing Compound.
That seems to work on minor marks for me.
It also takes the wax off, so you'll have to re-wax it afterwards.

EDIT: Polishing Compound? Rubbing Compund? I forget what it's called exactly, but it comes in a short green cylindrical container (~1 inch high ~4 inches diameter).

 

Do you mean water blade? I would get some 3M Scratch and Swirl Remover, that will fix your problem.
