when theres just that little dab they put on when new, the cable slides past it and picks up some as it moves, when you spray it on thick over time dust and dirt will get into the grease and then jam the guts where the cable spools up, then the cable breaks from the grinding of dirt in the grease.
i went through 2 regulators in my last truck in one year, i greased the crap out of them both, ( white lithium) the last one i used the graphite lock spray and it lasted over 3 years, same one was still there when i sold it.
