Some of us live near a Harley Davidson dealer and we all know S100 and
P21S have a few products that are quite similar. (same???)
The carnaubas by each company is in the same white/blue plastic container.
S100 makes a
gel wheel cleaner thats probably a rebranded
P21S gel wheel cleaner.
I bought some yesterday, 14 bucks.
So, check out your local Harley dealership (Steve Drane on Cloverdale in Victoria for me). You may discover a few products you won't have to mail order,
