Diamond-cut wheel PPF?

[Robertb]

I had my Mercedes diamond-cut wheels refurbed a year ago and annoyingly the finish is already starting to go on two of the wheels. The company have offered to do them again, but it looks like they've failed around the centre-caps and the bolt-holes. I wonder if this is due to the lacquer on the edges getting damaged/lifted when I had the rear tyres changed, even though the tyre fitter took great care (I was looking over his shoulder!)

I'm guessing getting the lacquer to bond properly on sharp edges is difficult.

Is there any merit in getting some PPF applied in these areas?

My advice is to have them powder coated instead as diamond cut just doesn't last however well it's done or protected. You're going to run out of material anyway which makes the likelihood of failure even greater.

I'm considering that actually... the annoyance is that one wheel is relatively new OE Mercedes and in perfect condition so I'm loath to have it painted.

They are the 'turbine' design which has a diamond cut face and black 'blades' and they look really good with the black car, not sure if it would be possible to duplicate with paint. I guess a single colour might make a nice change.

Diamond Cut wheels are a stupid idea. They pretty much always go scabby.

The 20" ones on our GLC looked st and were corroded after 5 years



I had them powder coated in Shadow Chrome instead, for £400. Miles better and much harder wearing !

That looks really smart.
Presumably it’s not possible to powdercoat two colours on a wheel?

Good question. Can you multi colour powder coat or is that just for diamond cut wheels?

Just googled it. Apparently you can.

Interesting… I’ll ask the wheel place when it goes in.

Always wondered what the correct term was, thanks for that.
They look very good and going to be a much harder wearing finish, fair cost too, little more than a basic powder coating finish which looks dull as dishwater by comparison.
