Took a wheel off the Boxster today as I thought I may as well have a go at refurbishing a wheel while the country is on lockdown.

I’d noticed a bubble in the back of the wheel when washing the car a few months ago and thought that the wheel had some sort of protection film inside the drum but turns out it was the coating that was making the noise as it’s let go of the drum. The whole of the inside is peeling away.


 
Oh dear looks like you've got your work cut out there.

All that loose stuff wants pressure washing off, or even media blasting to get it back to sound metal.
I guess you could get some sanding pads on the orbital sander/ DA ?
 
I certainly do. I’m not sure what to do with it yet. I might just take off the loose stuff with a scraper first to keep the mess down and then see which sander works out best. Failing that I’ll take the putter drums to a local shop for dipping or blasting if it’s too much.
 
that coating doesn't look normal - maybe after-market or a previous attempt at a repair job? could be a lot of nasties under that - best of luck with it.

 
I’m hoping there’s nothing hiding and it was just a poor refurb in the past that’s let the weather in. Fingers crossed.
 
Managed to separate the wheel today. There’s a clear line around the insert where the previous coating was removed to polish the outer lip. This has made an easy path for water to get under the coating. I’ll start removing the coating on both parts now and hopefully get them looking A bit better.



 
That corrosion looks pretty serious to me.

I would get them inspected by a qualified technician as they may prove to be beyond a safe repair.
 
I agree, a lot of deep pitting and corrosion.
The 'lads around the corner' wheel refurbishers might clean, dip, shot blast and powder coat but I think these need much more than that.
I would look for other wheels, might be the cheapest and most reliable result.
Good luck, let us know what you do.
 
Had the tyre removed today so that I can check every part of the barrel.


Although the corrosion looked terrible with a very light gentle sand I was back to clean undamaged metal.

It would appear that the powder we could see was the primer. It’s just reacted badly with the weather and turned to dust between the wheel and the top coat.

Once I have removed all the paint and debris from the wheel I will take it to have it checked. It could be a case of just replacing the barrel as the centre is in good condition.
 
Just a quick update. Been doing a day here and there on the wheel refurb and the outer barrel is now finished.


I had the barrel looked at by a specialist firm once I had stripped all of the paint and debris. The corrosion was the coatings and there was no damage at all to the metal of the barrel.


It’s now been painted in a bright silver with a number of coats of clear then polished with Poorboys Wheel Sealant.


Ill now concentrate on the insert and post pictures of the completed wheel.


 
Good to read.
Just been through the same on my Box rims, lots of peeling and bubbles of the paint lifting, but all 'surface' corrosion.
I used UPOL etch primer and silver paint from UPOL too, job done.
Not perfect, but ready for another year, then a full pro strip and powder paint late next year.
 
Nice job Peter. A lot of work to get to that stage though, but very satisfying I would think?

Only three more to go..!

Nice job do you have any photos?

ive watched many many youtube videos I’m hoping that I can do the job as well as the professionals if I take my time and save myself a fortune.

my paints have all come from wheelpaints.com
 
Great work on the barrel pgups !!

Looks like you've got a great finish.

Fair play on taking your time, like you say, without rushing and with no particular deadline you could get better results than you'd get paying for them.

 
I spent some time today cleaning and polishing the bolts which go around the outside and secure the insert to the barrel.

I'm not sure if this is the right way or the wrong way but it worked for me so thought I would share in case anyone is doing the same.

I placed the bolt in my cordless drill and went at it with a small wire brush and then held a piece of 3000 grit wet and dry (wet) against the top.




 
Finished the wheel today and got it all back together ready to go back on the car in time for the MOT Wednesday.
