2019 i30 N-line+: modification help!

[LiDix68]

Recently bought an i30 N-line+. Anyone got knowledge or experience of window tinting? Wanting to add privacy glass tint as I don’t like the rear windows being clear. Do Hyundai sell the tint or will it be an after market job?

Also wanting tips on dechroming the window surrounds to match the gloss black parts.

Cheers!!
