Hello,
Decided to get some GMC parts powder coated. I believe that this is very hard wearing, and resistant to chemicals etc.
I called a local powder coater, and asked how much for the metal door panel gave him the size!, he said $25, and if i had lots of stuff would be cheaper in the long run....
So the metal door panel & Alum handle, heating vents, the seat bases, the front rear mirror mount, are all off next week for coating.
Thinking of getting the OEM wheels powder coated also, until i can find a used cheap set of alum ones !!!!
Would that affect the tire pressure at all??
Any thoughts on this please.
cheers and beers

Powder coating is great stuff. It does exhibit some chalking from UV exposure. You can solve that by waxing it.
It's thicker than solvent based paints. Other than that, I don't see why it won't be great on wheels.

I am told that powdercoating may chip and when it does, repairs are not as easy to make as paint. I wonder if wheel weight installation and removal might cause chipping.

Wheels need to be plated against rust prior to painting and powder coating
chips easily (if not plated corrosion will occur underneath the paint,
powder coating is pourous. wheels are better painted with 2 pack urethane it
is more flexable as well as hard.

Hello,
UV chalking :- Wonder how long that takes months, years ??.
I wonder if applying UV resistant coating from time to time would alleviate that problem??. Now you mentione that, i remembered i had seen many years ago, powder coating on some metal work that lived outside, it looked chalky, so UV did that. "You learn something new everyday." Wheel weights, could see how they might scratch the coating... Was thinking of getting the A-Arms etc done also to match. Any known effect on the ability of tires to seal correctly, with the coating applied ???. Would make the wheels look rather nice, but do not want to splash out, if its only gonna look good for a short while ???
cheers and beers

The easy way to eliminate chipping from wheel weights is to eliminate them, use balancing beads or powder. However use of the OEM hubcaps would also lead to scratching and chipping.

We powder coat many components such as appliance dollies and have also tried wheels. It requires all of the same cautions as most other paints and although it can provide a great finish, it is not a majic solution for corrosion, chipping or fading. Many cars and trucks are powder coated as a way to meet emission requirements for the paint shops.

Only if you powder coat the wheels and put them into the curing oven with
the tires still on them.

The wheels on my recently acquired Palm Beach were disgusting looking so I had them sand blasted and powder coated. I love the result but when I installed the first hub cap I could see they were going to chip and scratch the powder coated finish so I decided to go with the "non-hub-cap" look. Now I am going to clean and paint everything inside the wheel wells black, including my lug nuts. I also powder coated my old hub covers with a matching green which I think will really set it off. I will post some pictures when I get one side done. That also frees up a bunch of hub caps in case anyone needs any. I have about 10 of them in various conditions.

Most of the powder coated parts for my rear suspension ended up that way due to the cost of sand blasting. The cost to blast the parts was 60 percent or so of the total cost to blast and powder coat. Originally I was planning to have bogie parts blasted then top coat with automotive paint but it just diddnt make sense (to me anyway) to not have the whole thing done since the powder cost was same or less than my material+labor costs.

I now of a collection of mostly ugly 16" wheels, I went around locally for quotes to sand blast and powder coat 7 and it was close to what JimK would charge for hub centered alloy. I'm still planning to sand blast at a really inexpensive shop and squirt so primer on them myself. I would have liked the powder coat.

I am so not a fan of powder coating.
I firmly believe the industry has the public snowed.
It has a sexy new(ish) name that sounds so cool and hi tech, it must be better right??
The only real advantage of powder coating is that it's cleaner, no solvents and the over spray sweeps up.
Durability wise a good polyurethane paint is far superior.
They are both tough and temperature resistant, but urethane Is more flexible, has a chemical bond to the substrate rather than a mechanical bond, it's repairable, better UV protection, and it looks better. It's also low temperature, no need to bake the snot out of your part (like 450 degrees)
And its repairable, just spray some more on top....lets see you fix powder coating...
I own my own powder coater and do use it.
But 2 part urethane is better.
Did I mention paint is repairable??

Many of the commercial powder coaters in this area prefer to do the media
blasting in house. They have several media that they use, from silicon
carbide, aluminum oxide, glass beads, walnut shells, soda, etc. The powder
coating should be applied as soon as possible after media blasting and
metal prepping. That way they know that some grease monkey has not been
handling the parts with stuff on their hands that prevents good adhesion. I
personally have a powder coating outfit that I use for parts that are small
enough to go in a 42" electric range oven. I have one in my shop that I use
exclusively for that purpose. I also have a glass beading cabinet that uses
compressed air to blast the surfaces of parts with glass beads to remove
rust and scale. I use non residual chlorinated hydrocarbons to clean the
parts before I powder coat them. On heavy castings like GMC knuckles that
have been subjected to chassis grease, I first bake them in the oven for a
couple of hours, then let them cool off before I final clean them and
powder coat them. I have done quite a lot of it over the years, and have
learned what does and what does not work. If it is not clean enough to eat
off of, it is not clean enough to powder coat. Some lessons I have learned
the hard way.

And as an addendum to this posting, I agree with Keith, on some things, 2
part catalyzed urethane paints are an incredibly durable coating properly
applied. And they can be touched up easily. Either method is very durable
when proper steps are used in their application. Powder coat has the
advantage of being able to be handled as soon as the parts are cool enough
to do so. Urethanes are soft until all the solvents find their way out, (or
the catalyzing process is complete). Just what I have found. Your
experiences may vary. But, I grew up using nitrocellulose lacquers and
enamels. Don't want to go back to them here in Oregon with all the moisture
in the air and wild temperature swings, but that being said, I was at an
indoor car show last weekend where a buddy of mine showed his 49 Merc lead
sled for the first time. About 40 coats of Candy Apple Red nitrocellulose
lacquer, wet sanded between every 5 coats. Nothing else even comes close to
that look. But the job cost 6 months wages, and took almost that long. I
don't have that much time left on my clock to invest in those paint jobs
any more. Still great to see old world craftsmanship though.

Powder coating has been around since the late 1940's.

Durability really depends on what material is being powder coating
Between 1958 and 1965, literally all powder coatings, generally only functional applications with a film thickness of 150 µm to 500 µm, were processed by means of fluidized-bed application. Electric insulation, corrosion and abrasion resistance were in the foreground. The coating materials in those days were comprised of nylon 11, CAB, polyethylene, plasticized PVC, polyester and chlorinated polyether, among others, and at the same time, thermosetting epoxides, e.g. for dishwasher baskets (PVC), for heat insulation (epoxide), for boat accessories (nylon) and metal furniture (PVC, CAB). It was the Bosch company that developed the basic type of epoxy resin powder in their search for a suitable electric insulation material.

I cannot understand how polyurethane could have a chemical bond to metal. I think that if you explore the subject you will find that it is also a mechanical bond.
I agree that there are a lot of applications when polyurethane would be simpler and better.
But an epoxy powder coating is a great coating for a lot of applications.

Keith,
I fell in love with powder coating when I had the wheels of my 47 Canadian Ford Monarch convertible done in a maize yellow to match the paint on the car. I owned the car for about 10 years and never had one problem with the coating. I also had a 46 Ford Commercial (1/2 ton) pick-up. Did all those wheels black, no problems. Then we had a patio set, 6 chairs and a table made of wrought iron. About every other year I would clean them up, get some rustoleum primer and paint and repaint them. Finally paid about 600 to get them powder coated a bright green to match our pergola and they have looked fantastic ever since. They sit outside all year long and still have that pristine green look.
So My experiences have been positive.

We did hundreds of thousand of paging horns in powder coat back in the day, and it was environmentally friendly, looked great.
Now when I see these quarter century old parts, they STILL look great, and you know the materials (and the color choices) are better than ever before.
I don't know if the same thing can be said for the new water soluble automotive finished.

If it is not clean enough to eat
off of, it is not clean enough to powder coat. Some lessons I have learned
the hard way.

Well, interestingly enough, AlumiGrip <tm> wouldn't stick to aluminum at all. We had to spray the plane with a wash primer first, to which it bonds like all the proverbial things.
