I'm about to attempt this on one of my 'verts. Basically, I have an entire quarter panel, both trunk floors, a quarter patch panel on the other side, and possibly the taillight panel. I'm going to practice on the floor pans and trunk floors, then apply the learned knowledge to the quarter panel patch. If it goes well, then I will try the entire quarter panel. Is there an order in which you can build your knowledge as you go?
I've talked with body shop guys about quarter panels, and they all seem to say it's not hard, just takes a lot of time and patience to get it all lined up. Especially with the repop stuff. From what I've seen, they estimate 8-16 hrs of labor for an entire panel, and they know what they are doing. HTH.
