what do folks use to preserve the finish on their diamond cut wheels, or any other fancy wheels for that matter?

I usually pressure wash wheels occasionally so brake dust build up is never really an issue. Washing with a wheel brush and car shampoo is enough.
However to delay the onset of corrosion, is there any special preservation product that is better than others?
Products like fluid film are great for preventing corrosion though I've never tried it on wheels.

I have previously just used up any old polish /wax products that are at hand, once a year when the wheels are taken off.

I think its a waste of time personally and having read many articles on this subject feel the only way is to have them stripped and powder coated.. eventually the spider webbing will win regardless.. in my case if the wheels got so bad and unsightly I would simply buy a set of after market wheels.. I personally think the wheels on their cars are not so nice looking anyway..

If the reasonable thick coating does not stop it, then I do not think that anything we could apply would stop it. As once it is underneath, then there is no stopping it.

Just bad design choice. Looks nice when new, but suffers from either bad production or just can not deal with surface dressed roads and the constant battering they give cars.

You only have to walk round car parks to see it covers every marquee going.

Thinking about it. I use ACF 50 to protect the bike. Spray/brush in hard to reach parts it on and just leave. It is not pretty as it is best left unwashed as the layers of dirt help to protect bike. Usually put in in autumn & clean off (real PIA) late spring.
Might work, but as they tend to dress roads in summer, that is when you would need it most.

I had the same issue with my Mercedes Wheels diamond cut looks nice when new but a real pain, I ended up having mine refinished in a gunmetal grey, which looked smart and didn't show the brake dust as much. As suggested Powder coat, but tricky with the two tone finish on the E-Niro's wheels.

this sounds like something that may actually delay corrosion for a while if applied to any small chips or dings straight away. I guess it could be wiped/buffed off so that no build up is visible while still leaving the ultra thin coating mentioned in their sales blurb.

I don't know if polish or wax prolongs the life of the wheels , but it sure makes it easier to keep them clean and brake dust free.

Trouble is while it might delay it, it is not going to help if you like clean wheels....

the uk your never going to win with our climate ,if you supply lacquer wheel it’s inevitable they will corrode within a couple of years and the manufacturer should accept the consequences ,alloy coated wheels covered in lacquer are always going to corrode,do you think a spray of a bit of lacquer is going to stop corrosion from anything .l,d pay the exta just to get a couple of coats of paint or as it is inevitable having to get the wheels powder coated.

After the reading I did initially, I gave up on mine as a losing battle. Admittedly I've kerbed a couple but even before that, I could see it developing under what appeared unbroken lacquer. Now my theory is, keep the rest shiny and don't look at the wheels close up. It's not like you can see them when driving anyway. 😁

I still think if manufacturers are going to supply lacquer wheels in the uk they MUST BE prepared to replace them when they suffer from corrosion,how thick do you think the lacquer is and is it substantial enough to withstand any stone hat might fly up

It's a nice thought but hardly likely to happen. Perhaps it's time that the hack pack who like to be referred to as motoring journalists, did some investigative journalism and researched the number of complaints about wheel damage and the cost of repairs to these shiny diamond-cut alloys.

If the motoring press could make a case that these fashion-item sparkling wheels were in fact unfit for purpose, perhaps the manufacturers might begin sourcing some longer-lasting wheels that retained their appearance better and for longer than diamond-cut alloys?

The laquer coating is probably broken, pierced or porous somewhere if corrosion has started. Wiping vaseline oil or Fluid Film over the whole surface with a microfiber cloth probably will delay the corrosion for a while, just like it does on any other unpainted surface. Those 2 products repell water and supposedly creep in to micro cracks and crevasses.

I've always rubbed some silicone grease on the back side of the wheel , only the surface where it's tightened against the hub or brake disk. This has reduced corrosion in that small area anyway.The alloy wheel is functioning as a sacrificial anode when it's in contact with the steel components of the drive train.

My 2017 Sportage (30k miles) is nearly 4 years old, I've managed to keep all four wheels is excellent condition. (tempting fate :unsure: ) I've attached 1 photo, all other wheels are in a same condition though. My method consists of never letting the wheels get very dirty or contaminated with brake dust. After cleaning finish with a specialist wheel preservative spray. Conclusion is that it is possible to preserve the finish on diamond cut wheels, I guess its directly related to the cleaning effort expended.😂

Do you use a pressure washer?

Not diamond cut, but I kept my wheels pristine before I started pressure washing, after I started pressure washing regularly they started to get corrosion under the paint.

Anyone tried Auto Glym wheel protector or ArmourAll shield for wheels ?

the corrosion on my wheels has started on the inside, behind the spokes.
the wheels have been spray painted from the outside with a thick protective coating, however the backside of the spokes has a much thinner coating.

This is probably where an ACF 50 type product may help.

"The US Navy carried out tests using ACF-50 on the jets on their Aircraft Carriers. They found that ACF-50 so significantly reduced the corrosion they had previously experienced they now use ACF-50 all the time!"

...should be good enough for my alloys then

Wondering if its possible to rub down the affected diamond cut area and remove the spidering/corrosion.. mask up and recoat with a lacquer spray can..

Im pretty sure that would create a better appearance , but would not last very long, perhaps 1 year/winter before it was back to how it was.

Calcium, glass or sand blasting seems to be necessary to remove all the "corrosion".

However, it's definitely worth touching up small stone chips and spots ASAP. Probably the same clear-coat with the small touchup brushes that are available for bodywork. Maybe even perform a small cleanup with a dremil first.
