I applied 2 layers of Poorboys wheel sealant and finished with a layer of 915. I can already tell it works better as brake dust isn't really sticking to the rims.
nice one shady, plus it will be so easy to keep them clean, the dirt falls off nicely when you seal and wax your rims. did the wifes bmw wheels back in april/may time with a polish over with lime prime then a layer of blackmax glaze followed by 2 layers of jetseal 109 a layer of collinite 845 and 1 layer of rainforest rub to gloss it up a bit, proberly went over the top tbh but well worth it imho as when i come to clean them it takes minimal touching to get the brake dust off.
keep in mind shady that your wheels are polished and wont show the breakdust up as quickly as normal painted alloys. and keep adding a layer of wax every other wash to keep the protection topped up.
