so I was pumping gas, the pump didn't auto-stop and it overflowed all over my rear fender. I washed it at the car wash (brushless automatic) but I can still see some residue (can also still see some salt/dirt around the bumper, waste of $11!)

does gasoline eat paint like diesel does?

It'll be fine, just rewax it since the gas took all the protectant off. Thats really weird that happen to my subaru, twice. Both time while I was refilling out of town at two different stations. It never happens here at my home town and I've tried 6 different pumps.
=============
I was really pissed because the attendant wasn't even at the register when I had to go in to 1) complain and 2) get my receipt (since the pump was also out of receipt paper)

then he was all *******y about it and said "okay... what do you expect me to do about it?"
=============
I hate using old style pumps that always happens to me when I use them.

You have to watch the Sam's Club on VA Beach Boulevard too. They'll let a pump stay in use even though it's spilling gas all over the place (had that happen before I got my Outback). When I went to get the attendant she handed me a bottle of water to was the gas off my clothes and told me "it's been doing that." I had to go in and get the manager before they would close the pump down.
=============
it really depends how long the gas stayed on the car. Based on the evaporation rate of gas it shouldn't have been on for more than a few seconds. The worst you probably did is remove the wax from the car. Just put a new coat of wax on it and you should be fine.
