I bought some of the pump spray before I knew better and it is milky and has a film it leaves behind (maybe even a little sticky). The aerosol has no such film that is a bad thing and make everything work better. That stuff is good for so many different materials it is great. The Pump stuff sux major!
I did call Blakemore back then to find out what was wrong and they were the ones that told me they are not the same product. The stuff in the pump for sure does not make things slide better and I think will not help you casting distance or anything else IMHO.
