I used Finish Line Wet through the winter. I just switched back to White Lightning Clean Ride for the spring, summer, and fall. Finish Line Wet is great for keeping snow and salt off the chain (preventing rust), but attracts a lot of grit and gunk (increasing wear and reducing efficiency). I'm thinking about going to White Lightning Epic Ride next winter because of the Finish Line Wet gunking.

All three are available on Amazon in large jugs if I decide that the little bottles are too expensive.
