W204 amg wheels diamond cut alloys white worm

[rayaans]

Mine were originally diamond cut being a late C204. Were refurbished by the dealer before sale in OEM Merc Silver
Personally think they look much better than dark grey/black on a white car to be honest.

Hi
I have the dreaded white worm on my diamond cut alloys, was looking to get power coat gloss black. Anyone done this or have any other recommendations

Yep, I had mine powder coated gloss black after getting the white worm starting. But having had mine done for a month now, you do need to heed Gazwould's advice and buy shares in a tyre shine company. However you will find that as the wheels get dirty so do the tyres, you will just need to tyre shine up every time you clean your wheels!

See my #7 There has to be something that can be done to prevent this worsening,/ to control it from becoming a big problem, before refurbishing is the only solution. Does anyone have the answer, perhaps one of our more astute detailers on here?

The problem is the white worm isn't on the surface of the lacquer, it's between the lacquer and the bare metal that is 'worming' it's way around and lifting the lacquer from underneath, so short of removing the lacquer entirely I don't think there is much you can do with it.

Ive heard good things about a tyre coating - TUF shine. Requires some prep but you don't have to put it on every time you wash being a coating and not a dressing. Worth a look?

I'll look into it. I previously used Blackfire which was good but expensive. I'm currently drowning them in Meguiars, so I'll do a bit of research into TUF and report back.

Drifting off topic slightly, but I'm hesitant about using tyre black/shine as I read that some of the products can cause premature degradation of the tyre sidewalls. Has anyone else ever heard of this?

If anything I'd heard the opposite. Most decent brands (if you believe the blurb) have UV protection which should help protect the sidewalls from getting a sun tan.

Diamond cut, or polished finish looks great though. Sure it's relatively weak from a durability perspective, but if you're lucky and treat the wheels well then you should get 3+ years before the white worm begins to show, quite easily longer.

It wasn't that long ago that only specialised wheel refurbers could repair diamond cut, now pretty much everyone can do it, so costs have come down to, or at least very close, to a regular wheel refurb.

For this reason I'd get them diamond cut again. When the sun shines on a polished alloy wheel face with no paint (only lacquer) on it, you can't beat the shine.

I had the dealer refurb all four alloys on my W212 before I agreed to buy it (approved used), diamond cut as it left the factory, and the quality of work (third party local refurber) is near as dammit to that of a factory finish. If they last as long as the originals I'll be happy.

I totally agree on the superior look of shiny diamond cuts.

I also agree that treating the wheels well is the answer to longevity. Mine are seven years old and only yesterday when washing the car did I notice the first sign of “white worm” on one wheel near the centre cap. It may be that I’ve been lucky, or it may be that the car isn’t exposed to the elements any more than necessary because I always garage it when not in use. But I like to think that the main reason they’ve lasted so well is that I’ve never used anything other than standard bodywork wash n wax shampoo and water to clean them.

A wife and kerbs have taken a bit of a toll in a couple of places however, so I might consider a refurb. The first couple of little scrapes in the early days I rubbed down very gently (a slow process, taking care not to abrade any further than necessary) then gave a few coats of lacquer - they still look fine many years later. But a few more kerbs jumping out in front of my wife, and now the first signs of white worm, make me think it’s time to get the wheels back up to the same “like new” quality of the rest of the car. I’d certainly get them diamond cut again.

I had mine refurbed anthracite grey, much better for not showing brake dust after a couple of miles!

I went for anthracite as well for the same reason
