Check out my build...car was jacked all up but my body guy got her to like new again. I replaced mine because it was hit and they used a ton of Bondo. I can hook you up with my body guy if you want all the details but he is anal about his work and goes the distance. Right now he is testing different black paints to get the deepest wettest effect
I did see a qtr panel replace on a 96 SS at a GM body shop once. The rear pillar cut was in the middle of it. rear and rear quarter glass was out. The pillar graft was lead filled after weld and finished smooth as glass. when the repair was done it looked exactly like stock on all the edges of door & trunk
