The problem i have with these products is that once they are compromised you have to clean the wheels, often with a cleaner to get them back to a condition where you can reapply it with out "sealing in" brake dust etc. Often we are talking 3 weeks or less on performance brakes!
Personally thats why i find a durable sealant like EGP works so well, yeah it wont repel brake dust like its a polor oppersite. But what does build up wipes away in a second, month after month before its compromised.
Thats months, before im back with wheel cleaners and lots of brush time! Other wise its a mitt and ez detailer for the barrels at the wash stage for me.
Cant help but recommend a spritz of UQD on the wheels after the sealant as it inhibits build up even more! Also EGP is water like, easy to apply with a finger applicator!
I will see how this fairs if and when i get my hands on some!
