I might help to understand that Frog Lube isn't an oil. It's not a fluid that needs to be in liquid form on the parts of the gun to provide a film of lubricant. It's a metal treatment. It seeps into the pores of the metal and partially bonds with the metal to create a rust inhibitor and friction reducer. So you can't treat it like normal gun oil. You have to pre-treat the parts with frog lube and then wipe dry. In other words, follow the instructions.
A guy in Wisconsin just did an amazing independent test of something like 47 different products. I won't spoil the end, but it's about the most comprehensive test I've ever seen. He's a frequent poster at the Alaska Outdoor Forum. Here's a link:

Bottom line, there are 3 products for rust protection that won the test so handily that it's just ridiculous. Frog lube lasted 54 days exposed to the elements, Hornady One Shot lasted 58 days, and WD40 Specialist Corrosion Inhibitor lasted an impressive 62 days before significant rust showed. Most of the traditional "gun lubes" lasted less than 12 days. Many of them failed in less than a week. For lubricity (yes that's a word) the winners were (in decending order) Hornady's One Shot, Frog Lube, and Rand CLP. So, you want a corrosion protection and lubricator? Hornady's One Shot or Frog Lube.
