i use frog lube too"Bleudg"I've been using the Frog Lube/Oil on all my guns and my shop tools. All of them have been out in my shop with no heating or A/C. Have thought about getting a De-humidifier but so far I haven't had an issue with rust! Frog Oil does have an issue (sticky buildup) if you over use it. I check things over every month or so and "lightly" apply if necessary and then wipe down. The only down side is the price. I use the preoiled wipes ($8.00 at Field & Stream) and they seem to last longer.

TDKI read a bunch of threads and tests a while back and ended up trying CorrosionX. It is a very slick lubricant, safe on rubber/plastic, and really sticks to metal. I'm still using it and swear by it. You will probably have to order it, though, as it can be difficult to find in stores.
"KzooRichie"I dug up one of the reviews. This one seemed pretty through and was the one the persuaded me to buy the WD 40 rust prevent.
