i haved used the same wax for over a year, same tube accually, and the last time i waxed my car it left a filmy residue on it that was extremely hard to get off, what caused my wax to do this

 

What kind of wax or polish is it? Did you apply it too thick? Did you apply it in the sun or to a hot surface? How long did you let it sit before you buffed it off? What did you use to try to remove the residue?

There could be a hundred reasons without being a little more specific...

its turtle wax hard shell, it was about 70 degrees out, my car was in the shade, let it on for about 15 minutes, i didn't put it on too thick

 

Sounds like the product itself has gone bad, it could have been 2 or 3 years old when you bought it.
