Where can i get my car polished?
Any car detailer or valeter can polish your car and will likely offer the service. Some body-shops will do it too.
The trick is finding somebody who is good at it. Most are good, but as we have seen some shockingly bad attempts at polishing, not all are good.
We would suggest that you look for a reputable, well established company with a reasonable amount of Google reviews and who have published pictures or videos of their work on social media.
