Stopping rust under paint?

I got the same issues on my Duster Bubbling around the rear drivers lower quarter panel. and behind the front fender drivers side. I am going to order full quarter skins from AMD and get a new front fender. I want to eliminate the rust out completely. For however much it will end up costing me to do this, it will be worth it in the long run because I will get it all removed and hopefully I will never have to deal with the damn rust again.
