Wheels

[lorena]

Can anyone tell me how I am getting these marks on my wheels. No cerbs hit. Only on chrome part of wheels.

Thanks

Are they diamond cut? If so it might be corrosion happening under the lacquer

It looks like the lacquer is lifting. I'd say water is getting in from the edges of the metal where the lacquer is thinnest.

Thanks for the replys. Would the spray wax at the car wash cause this or the stuff they put on the tyers.

 

[cliffcoggin]

No. I'd say either the lacquer is too thin to spread around sharp edges or the preparation/priming was inadequate.

I think this definitely looks like moisture creeping in under the lacquer. This is a common site these days on modern alloys and in my experience the only answer is to have them re-furbished and as part of that process have the wheels protected by the specialists carrying out the work. 

[lorena]

Yeah, I have sent pictures to specialist near me for a price. Just takes the look of them when they look like that especially when the sun is shining on them

White worm corrosion, so lacquer lifted and oxide corrosion on the alloy. Certain acid-based wheel cleaners are known to be too aggressive, especially if you don’t wash the car yourself?

Couple of options, get them diamond recut, can only be done couple of times, or opt to get them powder coated. Powder coated is more hardwearing.

Another option, and probably more expensive is get a winter set of wheels. Road salt kills diamond cut wheels! So use them during summer only and wash by hand with a neutral PH shampoo and avoid car washes or drive throughs where you have no idea what’s being used.
