It’s been bothering me since the day I bought the car and I already bought a roll of 3M black vinyl wrap but I don’t know where to start or how to remove the existing vinyl.

 

For the cleanest look, I would remove the reveal moulding and wrap it on the bench. However, it appears to be a PITA to get the reveal off the door.

Alternatively, this may be better left to a shop.

 

I removed all 4 of mine and stripped off what was left on. Then I took them to a place that does vehicle wraps and had them wrapped in gloss black.

 

I would remove and replace with a new one, which is what I plan on doing with my passenger front

I believe it is just several screws holding it on

OP, I have this part part available if interested (75756-50020). Brand new
