worse comes to worse ill pop them all out, in the box and fender bondo to make it all smooth as best as possible then rhino line the truck all the way around on the bottom lip of the truck and if i cant get the front fender good then ill just pick up a new fender. or was also looking at the fiberglass flared ones dont mind them at all.those dents won't just "pop" out. if you try to pop them out, they are going to look worse than they do now. i know from experience.
you will end up with dents and wrinkles pushing out with most of the dent still there. then it looks like you dented it and did a crappy job of trying to straighten it out.
