Re-pop sheet metal

I'm working on my wife's project and having some kind of miserable time with this re-pop metal crap. Has anyone ever had any luck with that? Every car I've ever done I've had fits with it. It's so far off it makes your head spin, how do they come up with this, just eye ball it, make it, never check it and call it a day :banghead:

I need a drink or 10 :drinkers::drinkers::drinkers:
