At least it's not an old school steel tracking arm across your bonnet! Yep, actually happened!
I'm sure it'll be fine. Just make sure you ask how they're repairing it, what might/will be replaced and what/where will be sprayed. In addition, when you take it to them, to around the car with them and note down any issues you are aware of. Give them a copy and keep one for yourself - make sure you and the garage sign it - this is as much for them as for you!
Once you get it back, check the car over again and check over what they agreed to sort - make sure any paint matches and make sure it's not a sh...rubbish match. Stand back and go up close and look at it from all angles. Only take the car back if you're happy. Tell them you will draw up some form of words to state that the work carried out to an accidental incident was repaired to a satisfactory standard and you consider the matter finished. The garage's work is acceptable as full and final settlement of rectification.
I just hope they do a good job.
