925 is Collinite's Marine Wax and 845 is the Insulator Wax that most people use for vehicles. For all I know, they may be the same thing in different packaging for different markets.
I was never able to find 845 in this area and ended up ordering it on-line from Advance Auto Parts. Seems like it was close to $20 with shipping.
They are the exact same wax. I got this directly from Collinite Customer Service. Just for your info 476s Super Double Coat and 855 Fleet Wax are also the same waxes. They repackage for the marine market.
