Restoring old rims

Post by RockyF75 »

I tried some ford specific forums but the best answers I can get is "take it to someone that does rim restoration" :roll: Well, duh.

Does anyone know how I would go about restoring these and polishing them up, like, what to use and how. I want to get all that crappy black paint off them and shine them up.

I have the same 15 X 7" rims on my ute.
Mine were quite shitty when I got them, they still had the white podercoat in the spokes (off an XD ESP) but some dick had put 'clip on' balance weights on them and they had corroded into the rim.

I used paint stripper to remove the white stuff and then set up a hub & stub axle with a motor and belt out of a tumble dryer from the tip.
It basically looked like a pottery wheel.
Then while spinning them at 50 or so RPM, I used wet & dry paper (wet) to sand them, started with 320 and progressed up to 1000. Then used Liquid Reflections to polish them.
Liquid Reflections shits all over ANY other metal polish I've ever used.

I have seen alloys restored professionally by a powdercoater.

They dipped them in a bath of dilute HF (hydrofluoric acid = nasty stuff) for 24hrs to remove corrosion etc. (Mag wheel cleaner should do the same)

Then they lightly bead/grit blasted the outer face.

Then powdercoated them.

Anyone can powdercoat a wheel :roll: .. That isn't restoring it though.
These wheels ONLY have powdercoat in the spokes. The rest is polished alloy.

Is that how they came out originally?

I wonder if a powder coater could just coat the spokes for us. Wouldn't mind having them look as original as possible.

There's a guy on the datnet forum that is a professional wheel restorer. Basically its a very long step down process, starting with degrease then mag wheel cleaner.

Then working your way through various grades of wet/dry with a mix of polishing compounds. Finishing off with a soft buffing wheel.

Have a dig on their forum - their search engine is, er, better than some others i've used... :roll:

Your wheels appear to be the same as mine were. White powder coat in the spokes and the inner part of the rim. All the bits that are now black on yours.
If you mask up the bits you DON'T want coated you can get them recoated..
Use heatproof tape though.
Originally the outer rim had a machine finish that was shiny.
I prefer the look of the older XY type globes in just raw alloy so I removed all the powdercoat from mine.

The pic below is how they looked when new.

Oh really??? :roll: :roll: :roll: :roll: :roll: :roll: :roll:
ANYONE has the gear to do powdercoating??? :lol: :lol: :lol: :lol: :lol:

As to which bits to powdercoat - ever heard of (masking) tape before? :roll: :roll: :roll: :roll: :roll: :roll: :roll:

Go throw your (teenage?) ego around elsewhere tool.





Rocky - 2-pack is more durable and has better adhesion and chip resistance than most powdercoating systems (a powdercoater told me this!!!). If they were my rims, I would etch prime the appropriate bits and then get them painted in 2-pack.

YES.. If you have an oven you can powdercoat at home. Static powder spray kits are available for less than $100..
But you missed my point.. IE: ANY POWDERCOATER can coat a wheel but that isn't restoring it.

Ummmm. yeah.. read my 3rd post with the pic of XD sedan.
Powdercoaters do just that ... POWDERCOAT.. they don't sand corrosion pits out OR polish wheels.

:rofl: Haven't been a teenager for 20 years. I have however had plenty of experience restoring GT Falcons and Globe mag wheels IE Bathurst's. NB My pic of my orange ute. :finger:

RockyF75 even stated he wanted to restore them "to original" and you advise him to paint them with 2 pack. :roll:
Rather than arguing with me why don't you read the question thoroughly and try to offer sound advice?

if you had done any powder coating urself you would realise that the masking tape wouldnt work very well at all when it gets baked in the oven at around 210 degress...i dont think he was throwing his teenage ego around anywhere he simply wants to restore them not re-paint them

I had a mate in Rocky who used to do alloy polishing. Capricorn Custom something was his business name. He polished everything from wheels to rocker covers, and all manner of engine parts.

He polished wheels by steam cleaning, then clamping on a lockable turntable, and used a hand held rotary buffing wheel, like one of those long flexible drive drills, and various grades or buffing rouge.

From manufacture, alloy wheels usually had a clear coat applied once polished. This helped maintain the original shine, but didnt allow you to polish them if corrosion got under the clear. It then had to be removed, and the alloy itself polished. Once done, it was reletively easy to maintain with normal alloy polish.

I have polished wheels using a buffing wheel, on a cuphead bolt, locked in place by locknuts, and using a normal hand drill. Its slow and laborious, but does get the job done in the end. For yours, you could try a combination of this and 2 pack.

Would bead blasting to get them clean hurt the alloy?? Anyone?
Mud makes excellent toothpaste.

Possibly with a custom mixed abrasive mix, but i wouldn't let any old hack try it...

I wouldn't bead blast mine.. No point making more work.. The surface has to be dead smooth to get a good shine.
I might Soda blast if I had to but I've always gotten good results with W&D paper used wet.
Here's a pic of the F100 wheels I put on my Zook.
Not as shiny as the wheels on my ute as I only put an hour or so into each of them. No point going overboard for wheels that cop mud and rock rash.

You can certainly mask off parts to powdercoat but they use either a glass cloth type tape or green high temp tape. I currently have the gear to powdercoat but am tied down currently building a custom size oven to do some bigger bits. Any powdercoater will be able to a variety of effects from two tone blends, masking, and some very cool colours.
