How to roll a fender lip?

My thinkin is.....if somebody whose in this hobby "hates" to spend 75 bucks on a tool.......they're in the wrong hobby.
I bought tools to make it easier next time. Also in hope i never need it. One is the ford spark plug extractor kit. The other is a set of left hand drill bits. Sadly i had to extract 7 spark plugs on one truck.
