Ok so why in my dealership in the UK do the techs put anti seize on the wheel bolts then????
I can understand the logic for race car applications but the average man in the street isn't going too impressed when he has to change a wheel in the pissing rain in the middle of winter and can't get the bolts off because they have seized on. We all know that the standard wheel changin kit in cars is pathetic, thats why all sensible q listers keep a decent sized breaker bar and torque wrench in the boot!!!!
