How do you roll in fender lips? Is there a special tool or something I should have? Working on my '40 and am trying to roll in the lips of my front fenders. I tried using a baseball bat but am not having much luck with it. Basically taped off the lip and tried using the bat to roll and pry at the same time. I am afraid to put too much pressure on it cause I feel like I am doing something wrong as is. Just seems like there is a better way to do this and figured if there was a tip or trick, someone on here will know it. I know this seems simple but I have spent most of my day on this and don't plan to give up til it's done (preferably right).
