Looking for suggestions on quarter panel repair

Thats an easy enough fix,cut the rust out....get it squared up to a good size that clears all the rust and cut a cimetrical hole in the quarter......you can do the same to the trunk extension behind the quarter if you would like but if you want it to just look cosmetically good from out side,then just do the quarter....anyhow,find a good chunk of sheet metal....lots of home for sale signs around you could get that are about the right thickness.....cut it to fit,tack it in place in the hole you cut out and then go through with your weld beads,grind the welds,do a finish coat of bondo to smooth it off.....people get scared when they here bondo but even a $30,000.00 car will have SOME bondo in it.......now yes,a gallon of bondo is no good,but for minor imperfections or for finishing work,thats fine....good luck!
