PPF has to go on bare paint. otherwise, it won’t stick.

How you dealing with the wheels and the brake dust and rust on them. As much as I like the bespoke matte wheels, I hate trying to keep them clean.
I cleaned mine this morning with a hose, wheels cleaner, scrubbed with a microfiber cloth brush. Nice’n clean. But the rotors were rusted right away(normal after they touch water) so I drove the car two blocks to clear them. Came back and the rust is already covered the wheel barrels. Wtf.
These matte wheels have a grit finish and not smooth, what a pita! I’m about to call the parts department and ask for a set of the 10 split spoke wheels.

So I'm guessing no Glass Coat over PPF areas
Id ask the dealer but I hate to be a pain with more questions, I'm just antsy as hell waiting for my 500 to arrive
****s killing me 🤣
But then again doesn't $ 70 K plus have some leeway

If you go that route, trade someone on here and make a thousand bucks. (Or more.)

What do you think of the spray over the ceramic from day 1

It's a great idea, will boost the performance of the ceramic they apply and will help the base layer last longer. If you do that you won't even know when it eventually fails because you'll always have a top coat applied.

You can put whatever glass coat you want on the PPF.
So if they do it properly, PPF on bare paint. Then coat the PPF along with the entire car.

Any suggestions

I still break out the hose for them because the pressure helps. I do a rinse with the hose to remove any loose dust. Then I use a fallout remover (IronX or similar) and spray the wheels down, every surface including the caliper and whatever overspray ends up on the rotor. I give it a couple minutes to work on the wheels (usually by the time I finish spritzing the 4th wheel it's time to rinse the 1st wheel). Then I rinse the wheel again. This probably gets them 90% clean which is good enough for me. If it's been a while then I will agitate the fallout remover while it's on the wheel with an ONR soaked microfiber wheelie type pad before I rinse. Absolutely 100% under no circumstance allow fallout remover to dry on the surface, so only use on a cool wheel out of the sun. Then I dry with a wheel-dedicated microfiber towel.

I coated my wheels with Gtechnique C5 Wheel Armour so that helps a lot in getting them clean easily. I coated the inner barrel too but that surface is really rough even compared to the matte surface of the wheels, so I don't really know how good the coating worked in there. I don't worry too much about cleaning the barrels of the wheel to be honest. I just allow the fallout remover to do whatever it does, I don't even go into the barrels with the wheelie on a typical wash.

I find the matte wheels hide the brake dust pretty well unless you are looking at them in direct sunlight, in which case you tell they get that reddish/rusty-tinge to them.

I did discover the rear quarter panel caked in brake dust though, so I have experienced that now lol. I used the fallout remover on the rear quarter bumper area just behind the rear wheels as well to break down that dust before I hit it with the rinseless wash.

Personally I like the Optimum product line so I use their product called "Hyper-Seal" as a drying aid every couple of washes. It's also a great glass cleaner believe it or not

But realistcally you can use any Ceramic spray topper, they are all largely the same made of the same chemical compound that does all the heavy lifting (SiO2 - Silicon Di-Oxide). Some good ones:

Quote I received for my LC due in September is $10.5 which includes full PPF including inside lower doors panels, tint all around, and G2 techniq ceramic coating everywhere including wheel barrels. I have used G2 on other cars and it will easily last 8+ years IME. I use ONR to wash my car including wheels...been using it over 15 years with no issues ever.

I've done partial PPF in the past on my RS6 and an A4 and was never pleased so I am going all the way this time.

I've used G2 on 6 different cars and have not had to reapply on any of them and they all look like the day they were applied (oldest being 2016).

Whats your ONR technique for wheels? This is the one I still struggle with and bust out the hose for. My wheels are coated. Do you use just microfiber cloths that then don't return to the ONR bucket or do you use some other method? I don't want to have to use 3-4 microfiber every wash so I could use the big red sponge but the amount of dust just scares me in using my same ONR solution I use on the paint. Though I suppose I could do wheels last and then dump the bucket and clean the sponge properly.

I paid just shy of $6500 full Xpel PPF w/ Ceramic. The film is warrantied for 10 years although the ceramic just 4.

I use the cheap Costco Microfiber towels for my wheels. I wash the car first and then use the same ONR bucket for my wheels...if the MF towels get much brake dust on them then I just throw them away. Importantly I wash them separately from everything else. My RS6 had gigantic 16 inch rotors and 10 piston calipers and I never had any issues.

A high quality ceramic coating (the G2 techniq coating is warranted for 8 years) pretty much makes the brake dust a non issue....it easily washes off. Of course I wash my wheels at least every 2 weeks so there is no long term accumulation.
