Unfortunately it is really difficult to keep them clean, the
longer the task of thorough cleaning is left the more difficult
it is to restore the original finish. Strong chemical cleaners
become necessary but their continued use will damage the wheels.
Waxes and polishes only form a temporary cover that soon deteriorate
and have to be removed before reapplication meaning the wheels
are again subjected to chemical attack and tedious manual
removal.

Protex4 is a polymer coating that permanently bonds
on to the wheels and forms a highly effective barrier against
corrosive brake dust,salts and road grime. The hydrophobic
(water repellent) coating protects the surface of the wheels
and adds a further layer of stick resistant nano molecules
that keep an easy clean finish no matter what the interval
between washes.
