How do you etch the Chrome PVD to allow the PowderCoating to adhere? There are posts where the PVD peels off. Maybe better to remove it entirely. To me, a more reliable solution is a set of aftermarket black rims. I like the look of them too. But I ain’t letting Ford off the hook on warranty with the PVD. |

NOT even close to being a "powder coat process"...….
PVD (Physical Vapor Deposition) coating is an alternative to the standard chrome plating method used to coat aluminum vehicle rims. PVD is a layering method, which sandwiches a metal alloy in between a base and top coat of powder coating. A raw aluminum wheel is sprayed with a powder coat base. The wheel is then placed into a vacuumed chamber with a metal alloy cathode. The metal alloy cathode is then arced to create metallic ion plasma, which is then deposited onto the wheel in an even coating. Once the metallic coating is complete, the wheel is sprayed with a clear powder coat to ensure maximum durability. |

Below is from PPG in regards to their process of PVD and PPG is also the OEM supplier of the finish for Ford and many other OEM's. There is also a 56 page document on the PVD process but this is the short version.

Powder Coat is applied in a very simple negative charged part positive charged powder process, then fired or heated in a moving oven for volume applicators for small ones just a large single chamber oven most of the time. Have seen it done many times. It started in the oilfield industry to coat parts. PVD is even used on firearms and is one of the most durable firearm coatings that exists. |

I plasti dipped mine. Good enough until I buy new wheels.

Actually PVD finished wheels are not hard to strip at all. Simple sand blasting with a good quality media will have no problem.
We do it all the time at our powder coating shop. |

the simple powder coat is not nearly as durable over time as PVD.
Problem is, some powder coating shops do not take the time to do the work that needs to be done in order to make it good. We have to charge $100/wheel to powder coat because we have over 4 hours for a set of 4 wheels just to prep the wheels. The powder is cheap but on top of that you have the oven run. it is not cheap to run a propane fired convection oven for a batch. |

That statement is not correct. If the substrate is prepped correctly before powder coating the powder coat will last as good as anything out there, PVD included.

The reason they use PVD is that it provides a different finish. The PVD is a chrome finish and you can not get a good chrome finish with powder coat.
We have had to refinish many PVD finished wheels because the finish was peeling. But, that said, I have had to refinish a lot of powder coating jobs done by individuals doing powder coating in their garage that are not doing proper prep work and using cheap (Harbour Freight/Eastwood) equipment and home kitchen ovens for their process. Also, up here where we have much more severe winter conditions, the salt and brine solution they use to combat ice sure has it's effects on wheels, under carriages and body finishes that you don't see in your area. I am not trying to argue with you, I just notice you have some issue with powder coating. I have been in the powder coating business for over 20 years and my experience has been that if the substrate has been prepped properly, you use good quality powder and good application and curing equipment, the powder coat finish will stay as good if not better that most finishes out there. |
I do powder coating for a living. My policy on wheels is if they have every been mounted to tires they must be stripped. Silicone in the tire shines people use do not mesh with painting of any kind. I will send off the wheels to be chemically or hot sand stripped and then when they return they are ready to powder coat.
I tell people all the time on wheels, unless you really really like the wheels you have you would almost come out cheaper buying new than going through the process of stripping and powder coating. I am more on the industrial side of powder coating and don't charge a lot to paint them in our standard colors but as with all paint/powder coating jobs, the money is in the prep. |

. PVD is available in MANY colors lol. :) As I mentioned above it is being used now as one of the most durable finishes available for firearms. It is not for me but Kimber a firearms manufacturer makes colored weapons using PVD. Small mom and pop shops are not historically PVD processors/applicators if you will as it requires more much more capitol, investment in equipment, people and process. . This link is utilized only because it gives a good "overview" of what is available in todays market with respect to PVD and colors. In the end it is the individual who is having the work done and the more they are factually informed the better decision they can make as it is their throat their razor as they say. :) Last comment look for an ISO 9001 approved source if you are having PVD done. Yes more expensive most likely BUT you will have confidence the process is being performed as it should. https://www.bendplating.com/new-pvd-colors/ |
Update
Just a quick update, I decided to have a RetraxPro tonneu cover and Magna Flow exhaust with black tips installed instead of powder coating OEM wheels and exhaust. Pics coming soon! |

Check out the Lasco ford build on YouTube...he powder coated his oem rims.....very nice. |
