Has anyone used P21S on the black satin wheels yet? Any issues?

 

The standard P21S wheel cleaner is very mild, I'm sure it would be okay. In fact, it's so mild that you could also just use soap and water.

 

I'm using Sonax on my black wheels. It says acid free, but just in case, will I be OK?

 

Has anyone thought of taking the wheels off and coating them with Rejex so that brake dust can be removed by just a hose (in theory)?

 

It might help fill the pores slightly but at end of day the wheels get hot and the wax doesnt help 100%. Personally i think waxing wheels is a waste of time.

 

I've been using Rejex on the entire car and wheels for the past 10 years and it works great.
I even use it on the windows and works better than Rain x.
You put 2 coats on the wheels and let it cure overnight and the brake dust mostly washes off with little effort.
I use a boar hair brush with rubber backing for the wheels.

 

I can't answer how it will do on the GT4's black wheels but just wanted to reiterate the warning on the bottle: DO NOT LET IT DRY ON THE WHEEL!!
I once washed my car (one wheel happened to be in the sun) and let the Sonax sit on one of the wheels for just a few minutes. It had dried and permanently marked the wheel. It only happened once since I made sure to clean one wheel at a time after that. Otherwise I love the product and it works great. I wouldn't want to be the first guinea pig on the new wheels.

 

If you have the satin black wheels they make the break dust nearly invisible. LOL

 

Thanks... I was in the shade fortunately and let the Sonax sit for a couple minutes (it says on the back of the bottle, "let sit for 3-5 minutes") each wheel as I moved around the car. But didn't see any problems luckily.

Just curious, if not Sonax or P21s, what ARE people using to clean these wheels?

 

I may be missing something here, but are the black satin wheels simply painted and then clear coated, making them no different than a gray or silver painted wheel? Did they use a different coating process for the black wheels such as powder coating?

 

Great question.. The answer to that would determine how one should approach cleaning these black wheels.

 

I've just been using normal car wash soap (maybe a cheaper grade) with a dedicated bucket and wash mitt/brush. Unless you clean your wheels once a year, normal soap should be fine.

Hit any leftover tar spots with Goo Gone.

 

Claybar to remove Tar and Brake dust. Simply wash with hot water and soap.. -rinse & repeat..

 

Without knowing more about the wheel construction/finishing my 'hunch' is that any of the top-line non-acidic cleaners will be perfectly safe... As long as you follow the #1 golden rule for wheels which is only spray and clean one at a time, from start to finish. The only times I have ever gotten into trouble was when trying to cheat that rule and spraying one wheel with product to let it 'work' while cleaning another. It invariably gets problematic for me, whether it's wheel cleaner drying in the sun or simply not having the cleaner coating every inch of the wheel and working all the dirt... Which ONLY happens affectively when you move that product around with a brush (boars hair - perfect).

I don't believe in spray and walk away, because 1) it never seems to work for me. I always seem to end up re-spraying that wheel and cleaning it again; and 2) it just introduces unnecessary risk

 

I've used the Griot's wheel cleaner on all of my Porsche alloys. No issues over the last 8 years.
