That must suck. I coat my face with lard and then use coffee grounds to give me that 5 oclock shadow image so I don't get carded everywhere. It washes right off at the end of the day.
I've been using mach 3 forever but tried the '5 blade' whatever and it's freaking awesome! I got it in the mail and tried it. Fuck, they hook you that way. I wouldn't have thought 5 is better than 3 but fuck me in the ass, it is.
