Hot glue dent pull tips

Also I think i can take the fender liner out and get to the back of it which I think will help.

That would apply to the fender, but 99% of quarter panels have a wheelhouse in the way. Your reverse side access, if any, would be through the taillamp opening. (That would really only help if you invest in some decent PDR rods, which seems to not align with your goals for this car.)
