Rust Repair Maiden Voyage

It's been 18 months now, so here's the promised follow-up. The rear quarter looks the same as it did the day I finished this job. The car has only been washed/rained on a handful of times, but there's no sign of any rust at all in that area. So I'm calling that job a success.

The forward part where the quarter overlaps the rocker is a different story. The bubbling started under the new paint within weeks. If I had it to do over again, I'd pull the rocker trim and cut out more metal along the bottom of the quarter and maybe the rocker too.

One other lesson learned that I didn't realize until later: I got a good bit of overspray on the trunk (you can't see it, but it feels rough to the touch). Clearly I should have covered a much larger area of the car before I painted.
