so i finally got around to putting my stock wheels back on... and... well... just see for urself... i have no idea what it is and it won't come off w/ scrub'g or w/ wheel cleaner

they've just been sitting in my garage in bags since they came off for my winters from kal-tire

edit: left this info out:
sorry, i left some info out... basically it looks like mold... and i think it's under the clearcoat cuz when i tried to clean one of them, some clear plastic stuff flaked off the wheel

also, when u feel it, some spots feel perfectly smooth like there's nothing there but others feel hard like, i dunno, tartar? and others yet feel kinda gummy...

 

are they physical damage?
if cosmetic only, try claybaring it
see if that takes the "paint" out

 

first post edited for more info

 

that looks like your wheel is starting to oxidize... polished aluminum faces tend to do that... try a scrubby pad and some comet first, and then run some mcquires metal polish over it and a buffing wheel... that should get rid of most of it...

 

confirmed to be corrosion by someone i wouldn't question... *sigh*

 

Looks like they were laying down on the concrete and slid across it. Thus it fracture the clear coat and is now peeling and showing as white aluminum salt corrosion.

 

i should clarify, a veteran at my autoX club confirmed that it's corrosion and that it's UNDER the clear coat... so even if i go at it, i'll be spending quite some time on it... *Sigh*

 

You're not alone on this one man......pulled the L-sportlines out of the garage yesterday afternoon to put them on the car....the lip on one of them looks identical to your wheels! I didn't know what it was either, so i went at it with some CLR, and then decided to pull out a razor blade to test my theory of calcium buildup (from what though???). Neither worked, but this thread confirms my second hunch.

Plan on taking it into the rim shop on Monday.....
