I did this on my left front fender with the help a few Pelicans a few months ago. Things are a little fuzzy because the fender rolling was proceeded by significant beer consumption. As I recall, we used a piece of pipe with a lot of duct tape wrapped around it. We rolled the pipe from front to back several times to gently roll the lip up. We might have put some hand pressure on the top of the fender but I don't recall.
