I brought the Vespa ET4 in to a local body shop to get a quote for the paint. I gather they didn't want to deal with it, because they wanted $1,100 to do the job.
So, today I took it to Maaco, where they quoted the job for 60% less than that after I haggled with them a bit. That's a lot more reasonable, given that I don't want to spend any more time in my oven-hot garage than I have to right now.
Outside Maaco, they had a sweet looking Ford Galaxie freshly painted in red flake. It was tempting to have them do that to the Vespa.
Anyhow, hopefully they'll do a good job repairing the scratched. I'll find out for sure in about three days.
