I use PB Wheel Sealant on my True Forged wheels which have uncoated billet lips and painted centers. I can tell you with absolute confidence that it repels brake dust as good or better than any sealant that I've ever tried on them. Not to mention, it allows for very easy maintenance of the wheels and leaves no haze or "prints" behind on the bare aluminum. I usually just wipe them down with a microfiber and some PB waterless wash in between washes and my polished lips look like mirrors. The brake dust and road debris just wipes away leaving the polished finish behind and nothing else.
Here's a shot of one of my wheels when it was bran new.
Here is the same wheel now, after plenty of driving. It's been coated with PB's Wheel Sealant three or four times and other than that has had no major cleaning or polishing other than wiping it down with waterless wash and normal washing.
I've tried Klasse, Optimum and Black Diamon sealants on polished wheels and none of them provided the results that the PB's does. With most of the regular sealants, I've noticed that when I try to just wipe a wheel down with quick detailer or waterless wash, it leaves streaks and prints on the bare aluminum that requires polishing to remove. I don't get that at all with the PB's.
