yep unless you want to be redoing your car every other year then the only way is to get a new rear qtr and weld it in no two ways about it do not believe all the rubish you read on the tins of the rust eater rust neutraliser blah blah they are all all not gonna be a permanante fix they may hold it of a bit longer than no treatment but the only real way is an angle grinder sorry
