The majority of the cost there is time, despite the tons of special tools they have to reach up through narrow spaces to get behind a dent.

For those places they can't get behind the dent they use a hot glue method that works really well - essentially they use various sized disks that they glue to the dent and they slid a spring loaded puller over the disk and 'pop' the disk off the car, which pulls the dent. Then they massage the extrusion (extremely small) down flush. That method takes about 1 minute per dent but is not usable if the dent is 'sharp' and might cause the paint to come off.

The tech did mention that aluminum was a lot harder to work with.

I had an MR2 Spyder with significant hail damage to every body panel (probably at least 50 dents) and the end cost was about $2500.

GL - sorry to hear about it.
