Anyone experienced with powder coating?

I keep my recently restored jeep near the coast. it has original wagon wheels powder coated white. Within just a couple of months you could see rust spots. Figured it was poor prep work so the company repowdered them free of charge. Unfortunately the spots have returned. Am I wasting my time or should I try again? Full disclosure, the powder coater is not near the beach, should I find one familiar with the climate?

The spots really drive me crazy

Powder coat

We have a full line at work and I am the buyer for the powder.

The best thing to do is start with NEW unused wheels, we buy new powdercoated wheels for our trailers we build.

If you are coating something "used" the best thing you could do is DIP them and then use a hi solids zinc primer (powder coat) then coat the wheels.

The amount of build he is using is important also they could just be laying a thin coat of powder.

If the wheels had rust before that needs to be dipped if not the primer should do the trick maybe post a picture and I will show it to my PC guys they may have an idea

I don't think the wheels were dipped. Probably just media blasted to get the old finish and rust off. My guess is they went straight to powder, no primer.

I have bead blasted and powder coated my original wagon wheels as well. One of the problems with OEM wagon wheels is that they are two-piece welded together, rust likes to permeate through where the two pieces meet and is hard to get powder or paint into the crevices. I spent a considerable amount of time blasting each wheel in those areas so all rust would be eliminated before powdering.

After powdering, I used a body sealant in the cracks that I removed a year later because of discoloring. Now I just push paste wax in the crevices every year and have no signs of rust. You gotta do what you gotta do to keep water out in those areas because it is very difficult to get powder to flow into those tight crevices to begin with. Paint or powder, the results will be the same. Just keep it waxed but I know a lot of people will not take the time to do so, it is evident when you see chrome center caps on how pitted they become because no one bothers to wax them either. I do, and my originals always look brand new simply because they are waxed every time I take my wheels off for rotation.

If you want something to look nice years from now, you simply need to spend the time to keeping it cleaned and waxed.... period!

Keith, the waxing point is very valid, particularly the seem. I never thought about the need to do it. If I repowder, ill definitely be sure to stuff some wax in the seem.
