are called the "protector", there is a left and right. The theory is it protects the paint from the rubber weather strip under the roof. Im not sure it is worth it. I put them back on mine after paint because thats the way they came and I wanted to put it back that way. It's basicaly like that clear bra film. Also I noticed it looks like you don't have the handles in your rear deck finisher. If you get new handles and shave the locating pins off the bottom of them they won't break again. You paint looks fantastic BTW really awesome, well done!
