How to roll the rear quarter lip?

Thanks for the tips. I am not using the trim. That car has way too much chrome for me already, but it looks "wrong" to leave it off in many places...

Chip Foose likely has a LOT more experience using a bat (or roller) than I do :p
The tightest spot is always somewhere, of course. With my minitubs and springs relocated into the frame rail, definitely it's the outer lip at this point.

What size tires are on your Dart?
There's some videos on YouTube that I have watched.
