Are Viper wheels clear coated, sealed ?

[Black Adder]

2006 vert standard alloy wheels.
Last summer I was run off the road by a truck. Along with the rest of the damage, three of the wheels had a lot of cosmetic scratches that were polished out by a "Wheel Specialist". My car is professionally detailed regularly and today they noticed what looks like the start of surface corrosion on the three wheels that were refinished. The fourth wheel that was untouched does not exhibit the same signs.
Do the wheels have some form of protective finish on them to prevent corrosion?

They are clear coated.

If they re-finished it (machined down the gouges) and polished the entire wheel, they should have done a clear powdercoat at the end. I've seen some very good and some very bad wheel repairs on Viper's. The effort taken for the polish/clear coat will be the most important thing in making sure it looks like the factory finish.
