Need to roll my fenders
I've rolled, I've also done fender lip cutting.
If you choose to roll, you need to heat the fender lip up extremely hot so that the paint will become soft. The best way to heat it is using a radiating heater set at 1500 degree's (high setting) and put it about 6-10" away from the lip. then after a few minutes, touch to see that the panel is so hot it just about burns your fingers. then you can start slowly using a rubber/wood/polymer mallet to hammer up the lip. take your time and hammer it till it's flat against the inside. The heating radiator must be on this whole entire time you're doing. you must roll from where the fender meets the rear bumper line all the way over to the other side, completing a full 1/2 circle. If you do not, it will rub if you are running excessive offset rims like me (I'm running 10" wide rims with zero offset and 275 wide tires).
Others use fender rolling tool with a heat gun. My experience with that is it the paint cracks at the bend. The heat gun does not focus a wide enough heat source to distribute throughout the lip enough.
The recommended method for experienced cutters is actually completely cutting off the rear lip so it's flush. This guarantee's no paint chip/flaking. However, you need to know how to do it. You need an angle grinder or air cutoff tool and you have to slowly and steadily grind a line from start to end of the lip. You keep doing this back and forth till the lip finally cuts off. You do not want to focus on actually cutting it fully from start to finish because the paint will heat up so much that it will smoke and char right off. Or you can use a water spray bottle and keep spraying to cool it off if you choose to cut it from start to end.
The cutting techique is favored because it gives you an extra 4mm of tire clearance.

Did any of you guys with the fender roll and heat gun able to do it without the paint chipping later on? I've seen one z and one g that had it rolled and the paint cracked and flaked so the owners had to put touch up pain on it. I rolled my 240sx and it also flaked outta nowhere regardless of the heating. However I roll it till it's completely flattened, where others may only roll a 45 degrees.
thanks for the referrals guys! i really appreciate it

OP: i just returned from spring break. sorry about the delay, but your pm has been replied to.
thanks
