Perhaps there is some other coating of which you are referring. Powder coating provides your wheels and rims with better durability.
When you have the particles from the powder coating sprayed onto your rims then they go into an oven to bake at high heat levels.
Can you powder coat dirt bike rims. At the risk of being a know it all to the best of my knowledge steel ss cannot be anodized. One leave them in place and powder coat over them. Powder coating will come out shinnier than excels but it will not last as long.
I got 4 rims annodized at a local shop for 100 00 and turnded out great. There are two approaches to powder coating spoked or laced rims on cars motorcycles and bikes. Or two remove and powder coat separately.
The firm you choose will abrasive blast degrease prepare and powder coat the rims before sending them to you. In case you have aluminum rims and they were initially chrome plated until they lost their shine you will first have to get a chrome plate so that the nickel and chrome are removed chemically. This process causes the coating to fuse together creating a curing process that will help to add another level of durability to the product.
The paint of powder coating will be thicker also then you add clear coat to the mix and you will have a heavier rim that will have deeper scratches. An oxide coating anodization can be put on metals such as aluminum and titanium to name some common ones. Making the best decision.
They will chip and scratch a lot faster. Anodizing the rims is the preferred route.
