ok so im throwing some new fenders on my jeep to replace the twisted up ones that are one it. i am going to reuse the flares from the old ones (maybe). but from the fenders being basically folded in half, now the flares are a little out of shape. its really no big deal to go get some from the bone yard but if i can save a few bucks i will. is there any way to get them back into shape? heat?
