Query: Defective

I've gone through two bottles of B&B Prep and love it. Unfortunately, this bottle is not a clear spray liquid as it supposed to be but a thick viscous substance that will not even pour out of the bottle, much less spray. I did not try to use it until a couple of weeks after the return period had expired. But there is a quality control problem somewhere. I have never had this happen with a product before.
