Are powdercoated rims a good or bad idea? #705991

Howdy Guys,

I'm building (and customizing a little here and there) a 1970 A65L and I thought I'd give the bike a little pizazz by powdercoating the wheel rims and brake hubs gloss black and lacing them up with polished stainless steel spokes. I know I won't be the first to do this (I've seen pictures of several bikes like this) but I'm not positive that this is a good idea for a street bike. (I'm building it to ride on occasional weekends.)

I know that powdercoating is very hard and isn't "flexible" like epoxy paint is and I'm wondering if the powdercoating will start flaking off around the rim's holes where the spokes move a tiny amount with each road bump.

Your comments would be appreciated.

Post,pictures of the bike first. I'm not a fan of powder coated rims unless it compliments the vehicle.

Jimmie, you're going to have to imagine what it'll look like. I haven't done it yet.

Harvey Hi, I have black powder coated rims and grey powder coated hubs laced with stainless spokes, ( it cost a fair bit but worth it) this is on a B40 with red and chrome tank black frame, and I think and many have told me that it looks good. Think of it as a bit of individuality.

At the powder coat shop where I've had quite a bit of work done, the man there keeps several small rectangles of powder coated aluminum on the countertop. He told me they were there for people who think that powder coat is hard and brittle.

"Go ahead, pick it up and bend it back and forth. See if you can crack or split the coating" he said.

I tried it. The powder is flexible. I don't believe you will have any trouble with it cracking or peeling around your spoke nipples.

Unless it is fully vitrified powder coating I would never ever consider powder coating any paart of a motorcycle.
Particularly the rims.
Powder coating is an envelope type of coating and if it is compromised anywhere water will find its way beten the poweder coat & the steel a rust very fast.
First thing you will notice is the coating is a bit fluffy looking then it falls off in a big lump and is not repairable without a full strip & recoat.
As the wheel rotates the nipple goes in & out of the rim wearing the coating thin and eventually rubbing it off then you get excessive rust at the nipple hole where you want maximun strength.
OTOH if you never ride it powder coats are pretty.

what he said. companies went to powdercoat because its cheap, fast, and has no fumes. I've seen plenty of failed PC from bad prep and pinhole/rock damage that lets corrosion start under the coating. nothing beats good paint, except chrome

all the rage in hawaii for offroad bumpers and such 20yrs ago and it fails just as fast as paint in my experience, money in my view is better spent on s/s rims,but thats just my opinion

And yet, despite all the warnings given here, some guys are still so hypnotized by the powder-coating myth they will have it done anyway.

Plus, the available colors of the coatings are so limited matches to paint shades are almost impossible.

I have been powder coating frames,wheels and various small parts since powder coating been around without any problems. I now use it on my xs650 tanks. No problems.

Tony:
I had an uncle that lived in Bakersfield. As I remember, it has a arid climate.

It doesn't RAIN or SNOW there very often, does it?
Where it doesn't rain or snow, rust (or "rust creep under powder coating") doesn't occur, does it?

First not sure what to say other than I hope to hell you and the family are ok. These slow moving storms are brutal.
www.precisionpowerdcoat.org check out the gallery. Jeff has done a dump truck full of motorbike wheels some spokes and all. Even shitty rim- bands can be done with a texture finish and different % of gloss

And what I forgot to add to the origanl post, powder caoting s a process, like plating or painting.
There are a lot of diferent powder coatings from fully vitreous coatings that chemically bond the base metal and are bullet proof to 100% plastic which do not bond to the base metal at all, like on that cheap wire garden furniture.

Never had issue with powder coating but always selected by recommendation and knowledge of powder coating motorcycle parts, had my first part done 35 years ago and its still on the bike now. When I have garden gates done I have them zinc dipped then powder coated as not far from coast and salt, but no need for this on garaged bikes.

I didn't have my rims powdercoated, mostly due to the conflicting opinions y'all had about it. (And I can appreciate both sides of the argument!) But I still like the image in my head of having gloss black rims with stainless steel spokes.

Since my initial post back in 2017, I've discovered a process (which might be limited to US customers) called POR15. It's a spray-on process similar to paint but is impervious to chipping or water getting between the POR15 and the steel it's on.

Is anybody familiar with POR15? If so, your comments are appreciated!

Excellent process.
Professional restorers use it a lot on cars but it seems most motorcycle owners are too lazy to do the whole process on motorcycles.
I used to use a lot of POR 15 but not so much now days.
You must follow the instructions exactly.
And remember the base coat is not UV stable so while bullets bounce off it in the dark, it crumbles & falls off in the sunlight.
Thus it is good to use a light colour base , grey or white so when you put the top coat on you can be sure the base is fully covered.
Done properly the wheels will nevr ever rust again even if you leave them sitting in water for decades

I've done powder coat on a few bikes that I did with none of the problems mentioned. However the powdercoater I use will not do anything unless he does all the prep in his shop. I just clean the dirt and globs of grease off, he does the rest. If I'm doing a complete bike I send everything to him including the smaller parts that will need to match. On a smaller project with just a few small parts POR15 is good but depending on the part, paint will work just as well. Ive found in my area getting a frame blasted and painted costs almost as much as the powder coat job so cost isn't really a factor. That is unless you do the painting yourself, any significant painting I do looks like I did it so I try to avoid it if possible. I've seen some very nice painted frames, wheels, rims, etc but also some nice PC'd stuff too so it really comes down to what you think will look the best. I really wouldn't worry about what is better, done well both are good but PC will be tougher. Done badly both are bad but paint is easier to remove and do over.

I've done a frame with POR15 aerosol, I liked everything about it apart from it is quite a runny paint.

I also use Eastwoods Chassis Black, the gloss is quite runny, But I have found the satin to be nicer to spray and gives a more even coat without the chance of running if you load the paint on. I then lacquer it with Eastwoods 2k lacquer (in a tin again) its a proper 2 pack lacquer, once its mixed you have 2 days at best to use it, other wise it goes hard in the tin!! But the gloss finish is real sweet and it makes the satin black into a Deep gloss Jet black! (however not quite as tough as the POR15, but this could be becasue I stopped using eastwoods Primer and the key probably isn't quite as good without it.

Ref POR-15
I have used the POR-15 paint system quite extensively.
IMHO it is particularly good for frames.
I get to bare metal, degrease, then use a POR-15 product called Metal Ready--which is basically a phosphoric acid preparation which kills any rust spots.
Then two coats of POR-15 black applied by brush.
Using a brush enables you to get into all the nooks and crannies on the frame.
As it cures (not dries) the POR-15 seems to contract slightly and on a round frame tube seems to "tighten up" around the tube giving a really nice finish free of any brush marks.
As previously noted this paint is supposed to be UV sensitive---although I have used it on some outside house items and never noticed any efflorescence--white powder on the surface.
However to be on the safe side I then apply a coat of paint over the top of the POR-15.
POR-15 themselves produce a range of top coats and I normally use one of those.
When it is cured POR-15 is rock hard and very resistant to chipping.
It was originally designed for car chassis restoration and has an excellent reputation in car restoration circles.
It used to be made in New Jersey not far from where I live but a few years ago it was bought out by a company called Absolute Coatings and is now based in New York State.
I believe that the Eastwoods products which are similar may in fact be made by POR-15.
POR-15 is I think available in UK from Frosts.
BTW--I have no connection to POR-15 except as a satisfied customer.

The thin nature of POR 15 is one of the things I really like about it.
Being that thin is does not plug up threads and flows down into all the cracks & crevises.
Never used the spray can, did know they made one.
Always brushed on with a disposable brush cause once it dries out there is no rejuvinating an old paint brush.

Buy it in small cans and put a sheet of cling wrap over th lid before you reseal the can.
Any POR 15 left in the lip will seal the lid forever.

No complaints with it at all, just requires more patience when spraying. You may be able to get it in spray form in Oz, just depends what the importer brings in i guess, its like Eastwood products.... They do a lot more that what the UK importer brings in.
