Either painted or polished aluminum.

 

I would be extremely cautious using a power-ball on those rims. Both the painted and the polished factory '09 CTS-V rims are clear coated, and the clear coating may not hold up very well to the power-ball & polishes. & Do not use a metal polish on them. Wipe them down with a slightly damp rag, or wash them when you wash the car. Dry well, there are not processed metal parts on the assemblies.

 

i would echo the sentiment to be careful what polish/cleaner you use. One of the biggest lies on bottles is "safe for all wheels"--I nearly sued a company for this when a $5000 set of wheels was ruined (they replaced them)

Use the least abrasive thing you can--I use soap and water. I have used a power ball but it is still a PITA on V wheels --too many small openings. I have a set of polished and a set of chrome wheels for my V. Soap/water on both and Meguires chrome polish on chrome--no problem

 

Just curious. I'm assuming you did the chrome wheels yourself, as chrome is not an option from Caddy. What's the going price for chroming our wheels? And just how much better looking are they vs the polished,... subjective, I know?

 

I believe that they are referred to as polished.

 

Anyone have a part number for the polished wheels?

 

Only two options from the factory are polished or painted. The polished wheels get referred to as chrome quite a bit, but they aren't. They are clearcoated over polished surface, so do not use abrasives. If you want them to shine, hand-wax them with typical automotive wax.

 

Does anyone have a picture of an oem painted wheel?

I guess I have not seen one...

 

Does anyone have pictures of painted vrs polished???

I guess I have the polished...I am going to see what it would cost to get a set PermaStar'd...

 

Much appreciated! That really helps.
