If the scratch isn't huge, I think a can of the standard "alloy wheel silver" will do. Also, in the past I have used a touch up brush of Toyota Classic Silver on painted alloys. It looked fine - much better than the scratch itself.
I've also had a mobile rim guy come to my house to grind, polish and paint some curb rash on a another vehicle. He had all the right tools and paints. Total was like $80 for 3 pretty good scratches. I asked him do another one for $20 and he did. Maybe you can find a guy like that.
Luckily with the 225/60 tires on the OB, I haven't curbed a wheel yet.
