Alloy Wheels bubbling
Discussion
Hi all,
I've got a set of alloys (currently off the car) that are near perfect on the front but have some patches of bubbling on the back...pic attached of one of the offending areas.
I've got a couple of Qs and was hoping someone could help educate...
What actually causes bubbling, is it the paint/lacquer/wheel? They've been stored for a while and just odd that it's only at the back. Is it likely to be superficial or can it actually cause more serious damage? It does appear to be more surface...
If I sent them to pros, as it's just patches and at the rear, would they likely do it for cheaper or is the process the same for doing the whole wheel?
Was contemplating a bit of DIY...might be a useful to learn and as it's the backs could get away without perfection. Any advice on best process?
Thanks in advance...

Usually old stone chip damage allowing water & road salt access to the alloy itself.
Corrosion then begins under the paint & your get patches as in your pic often with spidery lines spreading across the surface under the paint.
Personally I'd go for a tyre off full refurb rather than messing about with little bits here & there.

Yep, the wheel finish has most likely become chipped & possibly road salt and/or alloy wheel cleaner has quietly done the rest over time. Depending on where you are, there are some cost effective places to get the wheels fully refurbished though I’d suggest that if you can, you leave it until the tyres need replacing.

I'm close to BJV and they are well priced and seem pretty decent. Tyres are now off as well which did make a difference!Cheers for the advice both
