Dude..What are you talking about...But yes...I actually am going to re-do it to a black material while its out.gonna paint headliner, while its out?
The headliner was removed to remove the Original Roof rack which bolts through the roof inside the car..It has to come down to remove the roof rack to install the smoothe rain channels.
To get the headliner out..you have to remove all of the panels you see out on the ground..Its a lot of work.
Ans you remove as much as possibble when painting a car for a better looking ,more OEM appearing job.
