Sorry never touched mine. On a different note, anytime I see these pictures I realize how lucky my cars have been to be in areas not using road salt.

sadly most uk cars exhibit the effects of salt after only a few years if used all year round...and lets face it 4wd is good in poorer conditions so lends itself to all year round use
