I USE A BRUSH ON BLACK ALL THE TIME -LAST 10 YEARS x5 cars

BUT…
its a special boars hair brush with a mahogany handle from either griots or Eastwood tool

the Ferrari club of America uses it on enzos and it will not scratch.
the key is it gets softer every time its used

whats the difference in retail?
griots gets $69 for the brush
Eastwood gets $35
