No, unfortunately circular polarizers kill any specular reflection that goes in. To do them you need a wide spectrum 45 deg phase delay film on top of the polarizer. You can buy the circular polarizer film, but note that it has a front/back (it's not symmetric). Another confusing attack is to put a camera behind a much larger half-slivered mirror... that does the job too because everything reflects... add a circular polarizer to that :^\
