Shahzeb excellent job done, your beetle looks so beautiful in bare steel that if I was you I would never have it painted, I would just have the whole body nicely buffed with an orbital polisher till its completely clean, put it in a baking booth and then apply several layers of clear coat / laquer and keep it that way, it would look absolutely stunning...
When getting the vehicle re-painted I would first get the inner sides of the fenders, doors, roof etc / all panels painted with a rust proofer to ensure longevity, after going through so much work it doesn't make sense to leave the parts you can't see exposed to the elements as potential rust magnets...
