Rolling fenders?

[Jam]

@Violator

Get a wood bat. ~$10 @ wallmart.

Jack up the car ,by the chassis, on corner you are working on.

Put it on a jack stand (recommended as safer) or get a second jack.

Put the jack under the suspension arm.

Lift the wheel till the clearance between tire and fender lip is maybe 1/2 more then bat thickness

Inflate the tire to 70-80psi

Put bat in gap. push handle end down lightly and turn tire slowly while allowing bat to rotate as it moves back and forth across length of wheel arch

You will need to make 20+ passes do do it well. The key is to TAKE YOUR TIME.

Do it slowly. No major bends at once. You can apply heat to help the paint bend but that doesnt always work. You will need to touch up the inner lips (not visible) anyway for corrosion protection

or you could go to innovative and get the proper tool for the job?
