mysterious staining on wheels

My crown court shoes have toe caps like one of your paint jobs ... ;)
 
It may have covered up the marks temporarily but the boot polish will need reapplying regularly as it will not be absorbed by metal as it would be by leather. At least you have found a way to mask the marks which is ideal if your selling your bike.

Agreed can only be a temporary fix , wont last long, will need reapplying every time you wash your wheels because you will wash it off! a traders trick;)
 
Are you guys speaking from experience or just guessing?

I WAS in this situation with my own bike and I DID replenish the finish with boot polish and it DID last more than two years. I sold the bike to a friend who has never had to touch the wheels again. The bleached alloy will take the pigment in from the boot polish. If the bike gets aggressively cleaned once a week then there might be the need to re-apply after a year or so but that's hardly regular.

Of course .... you could wipe some WD40 on it ....... that'll sort it right out :blast
 
Experience.

I did suggest trying WD40 as it can work wonders, not guaranteed though.

I would prefer to eliminate the marks rather than just cover them up.

Lots of products out there, it's trial and error until you find something that works or you could just try a quick fix.

Paintshop experienced, its not bleached alloy and boot polish wont last long on bare metal anyway, theres still coating on those rims, it wont last for to many cleans, we will have to see how the OP gets on wont we :D

It's bleached black anodising (not in the slightest bit paint related)

Yeah I guess we will ;)
 
Only just read this thread and If tunner says boot polish I would go with that !

To be pedantic you said "Alloy" in post #48 "The bleached alloy will take the pigment in from the boot polish"
Now you say (Correctly) it's anodised, and I havn't mentioned its paint related at all?
 
Can anodising take the pigment in the boot polish?

I'm not taking the piss, I genuinely don't know.

No, but you did point to your experience in a Paintshop.

Unless I'm misunderstanding / misreading, you believe anodising to be a different material to alloy?

Anodising is a process where alloy is coloured, it's a finishing process not a material. it's an electrochemical treatment. In the case of the OP's rim, they're made of alloy which has been anodised black. Certain chemicals can strip away the anodising leaving the bare (and slightly porous) alloy behind. There's no absolute fix for this, once the anodising is gone it's gone. The only real solution is to strip the wheel and have the rim re-anodised, failing that, the next best thing has to do I'm afraid.

Boot polish works well in this application because

1. Black is very easy to match - You'd struggle with red rims as an example
2. Boot polish has pigment within which will stain the porous alloy finish
3. Being wax based, the boot polish offers a bit of protection over the porous alloy thus helping to keep corrosion at bay

I not suggested that it's a permanent solution but as a fix it's just about as good as it gets.
As for it's durability, smear some on something porous and try to clean it off!!

Anyhow, I didn't want to get into a dick waving competition about who knows what etc, I'm just glad that the OP has got his wheel sorted.

I'll be leaving that at that :beerjug:
