Tips! How to roll rear wheel lip

I have done both rolling and cutting of the fender lip in the past. As has already been posted rolling the fender lip doesn't work very good with our Mopars the metal lip in the rear is double thick metal that is spot welding the inner and outer fender lip together. My preferred method is to cut/trim the under side of the fender lip with a cut off wheel. working slowly or with some water to cool the cut and not burn the paint off the outer fender lip. Depending on how much is trimmed you may need to tack weld and or seal that seam again.
