I wouldn't shoot any liquid other than water on the dash! And even then I wouldn't shoot it. What you have are 2 parts of the dash rubbing on each other. In my case it was caused by the dealership taking the dash apart to fix something. They didn't put it back together correctly. I complained and brought it back. They put another guy on the job that was a much better technician. The car was fine after that. I don't know what he did or what he took apart to fix it.
