Anyone used Gtechniq C5 Ceramic Wheel protector

Thoughts on the G5 three months on???

Sold the car that I put the 108’s on, but I won’t hesitate to to use it on the wheels on the new E89 that’ll I’ll be collecting... then I’ll let you know 3 months after that

Well I’m over 6 months now with the G5. It’s definitely a :thumbsdown: from me.

What do you clean the wheels with? From what I’ve been reading ceramic coatings are sensitive to the ph of certain snow foams, wheel cleaners and shampoos.

I tend to use Bilt & Hamber Surfex HD from a pump action pressure sprayer bottle. But really if C5 were doing it's job you would hope the brake dust would just blast off with a pressure washer. No chance of that.

What's perhaps more telling is that I actually only had enough C5 to do three wheels out of four. The is no discernible cleaning difference on the untreated wheel, in fact that was the case even within a couple of weeks of application.

Surfex HD is alkaline and is known to strip ceramic coatings, it may be that you stripped the coating nearly as quickly as you applied it.

There’s plenty on ‘detailer’s world’ about how Surfex HD can easily strip a ceramic coating, which may also explain why you see no difference between the 3 wheels you coated and the one you didn’t.

Hmmm, that's good info - thanks. I really only started to use Surfex HD when the brake dust really started to build up and couldn't be removed with just the pressure washer so it wasn't a factor in the early stages. But after a few weeks then certainly, yes it could have had an impact.
