ask the shop what temp they baked it at and for how long....
i have come to realize that most body shops "baked" isnt really that cured just cured enough to get the car out the door...
it really depends....
if it is something where they can high temp bake it (hood, trunk, fender, etc.) then its probably ok in a week or so...but anything that cant be removed from the car should not be waxed for 30-60 days like you said...
