I think Hyundai use G3 a ceramic based sealant (better than others) and it works - well at least it does on my 2 year old Santa Fe although I will probabaly strip off what remains in the next 12 months and do the job again myself. It's supposed to last 5 years but that's probably in a garage and only driven 6000 miles a year. I didn't pay anything for mine it was included as part of a price deal but £300 for an ix20? No way.

72 dudes is right the garage may not apply it correctly (they could do more damage than good if they overdo it with the orbital polisher) and not let it cure for the right time and in 6 months time it will be long gone so you're better off buying your own stuff and diy'ing it. Autoglym is good stuff but there are even better polishes and sealants that will do a superior job and protect longer but they cost a bit more.
