Had the roof, shark fin, and rain rails wrapped in 3M gloss black. Glad I decided to wrap the rain rails all the way down the A-pillar on the windshield. Think it flows better with the roof line. Have seen some without it and didn't look right to me. Matches the OEM paint job the lucky F90 M5 and F8x M3/M4s have with the CF roof.
Had looked into having it painted, but couple body shops told me it'd be more cost effective to wrap it
and would allow me to go back to stock for resale if I ever needed to.
