Well, the simple answer is "just go slow." And in essence, that's the most important thing. But the complex answer is to be more aware of the angle of attack of your roller. That is, pay attention to the location and angle of the roller head when you pull the fender. The further out you go, the more you want to gradually move the head up the fender slightly. A lot of people just pull and pull and pull away at the wheelwell's edge/lip and that puts undue stress along the surface of the qtr panel till the metal can't stretch any further and it buckles (or does the nice little *pop* dent). By pulling the fender across a broader area (not just from the edge of the lip alone), you're essentially moving/flaring more of the fender out... of course once you're a bit up, you're working more against the inner fender skin than the outer, but that's where going slow helps... cuz every little bit you can move the inner skin does move the outer skin out a tad also. And finally, it comes down to learning to "feel" when that metal is about to give. Going slow allows you to read the telltale signs and stop before it's too late, while it's a lot easier to get carried away when you're just cranking the roller back and forth, and next thing you know... uh OH
