Refurbing 19" wheels

[Jovie]

Hi I have just bought a C63 coupe with 19" wheels (not the black ones).
There is some kerbing on all four and I was planning on getting them refurbed, however when I looked closely I noticed that the wheels have a protective coating, quite thick and plastic like.
I'm thinking that if I get the wheels refurbed this will bestripped off and expose the wheels to corrosion.
Has anyone else had their wheels refurbed and the coating replaced?
Has anyone suffered from corrosion or 'milking' after getting a refurb?

On a slightly different note what are the black 'dots' on the rim lip for?

Surely if the wheels have been kerbed then the protective lacquer will be damaged and will no longer protect the rims so will need a refurb.

What I meant to ask is if anyone refurbs wheels and puts a clear laquer or whatever is on there now?
At the moment the only part being exposed to corrossion is the lip and i can have just that part refurbished rather than the whole wheel

The black dots... if there's one per wheel it's marking the low spot with regards to runout IIRC as it's impossible to produce a wheel that's perfectly round with zero runout. Similar deal to the red and/or yellow spots on the sidewall of new tyres which are to do with radial runout and the light spot respectively IIRC. The odds of finding a tyre fitter that both understands and follows these marks when fitting tyres are crazy, factor in the runout bands that go around the circumference of the tread and the odds are astronomical

Touching up the kerbing marks only might buy you some time but it'll probably only be putting off the inevitable as the milkyness is the result of oxidation spreading underneath the laquer and lifting it once it's been damaged by a stone chip or someone that can't park a car. Laquered finishes are fairly brittle as the high sheen/'diamond cut' finish is too smooth for it 'stick' to properly*. This is why you typically get far less of a warrenty for diamond cut/laquered refurbs

* relative to opaque paint finishes where the surface can be keyed (roughed up) properly to give the paint something to grab hold of. If the wheels are painted with a high sheen face or lip then typically they're done by painting the wheel, then machining the high sheen bits and finally laquering the entire wheel
