No, definitely want a ploarizing filter.

Perhaps they work differently than the polarized glass we used to play with back in physics. Withthese, light was only allowed to enter in a single plane. If you put two pieces togetherin the same orientation, light was largely unaffected. If you turned one of them 90 degrees, then one blocked out all the ‘vertical” light and the other would block out all the “horizontal”light. The nbet result was that no light passedthrough. I thought that perhaps a polarizing filter would work thesame way. I did see a Youtubevideo where a guy had a circlar polarizing filter and demo’ed it with exactly the same results I am describing. This is why I am a bit perplexed that the Hoya filter I purchased does not seem to do this. It has the free truningring in the front, but when looking through the filter by eye and turn the front ring, there is no perceptable difference. It is definitely labeled as a polarizing filter.

Try pointing the camera (with the filter on) at a reflection in a pane of glass (say at a 45 degree angle), then turn the ring and see what happens. If you don’t see a drastic difference (the reflection disappearing and what’s behind the glass showing through), then you don’t have a polarizing filter or you’re doing something (like the mounting) drastically wrong.

Perhaps you’re wanting a neutral density filter?
