I have some really big dents in the front fender of my camaro i was wondering if i should just try to push out the dent or if i should put on some other 3rd gen fenders i have? which is more work? I am geting it repainted in like 2 or 3 days.

 

Is there a crease in the dent? If not you should be able to pull the dent back out. If it is creased, replace. Espec if you already have backups.
