I cannot tell from the image. I even ran it in the larger size but it was worse.

I can say that depending on the construction of that strip it could be either a wick or a blade. One works during application (wick) and they both can work after application (wick or blade) and the wick can apply or resurface the coating. The blade can only resurface the coating. This is what my coating blades do, and what was done by Kodak in the 40s and earlier.
