Some kind of tape (electrical?) on doors

[aldumil]

Hi there guys, just joined the Mazda club (both in real life and here). I have a 2011 Mazda 3 hatchback. I was walking by it today what appeared to be tape caught my eye. Turns out their is electrical tape (or some kind of tape) running all around the windows of all four doors. I immediately started trying to take it off without thinking about it. It is proving to be a real pita to get off...

My question is, is this something that the manufacture does and it simply never got taken off? Or is did the previous owner do this for looks? (I assume to give it a dull-ish look all the way around the window...?). I really don't know how I didn't notice it before, lol. Anywho...thanks for any help anyone can offer.

Sorry if this isn't the right section to post this in by the way...

It is put on at the factory by Mazda. It is part of the exterior finish of the vehicle, and is used instead of painting the area black or using chrome trim. It is not meant to be taken off, but can be removed with some effort.

Woops, lol. It is shiny black underneath. Not as shiny as the rest of the vehicle, but that is probably because the rest of the car has been waxed
