Personally, I'd say your best bet would be to ask the shop what paint they used (the specifics) and find out what the manufacturer says.
If you don't wait as long as the manufacturer suggests, you're not going to have a leg to stand on if something fails. I'm not saying it will, I'm just saying you'll be on the hook- not only for the work you did, but for the paint/clear coat/etc. if it gets damaged, too.
