I find the froglube liquid dries out within a month and becomes all gummy. I lubed my shotty and thought I wiped out most of the excess but when I took it out to the range a month later in 3C temps, the hammer/trigger was so gummed up that the hammer would slowly lower itself after you pulled the trigger. I stripped the gun down, reheated the trigger assembly to soften up the Froglube and then flush it with some degreaser. My AR on the other hand worked well but to be fair, that rifle was stripped and clean only a couple weeks earlier so the lube wasn't dried out.
Similarly, I used to apply a small amount of Froglube on my 1911 slide after each cleaning and over the summer I guess it built up in the channel of the slide and got gummy to a point where you can see the slide slowly closing when you rack it or even firing it. Again, I had to heat up the parts and use a q-tip with alcohol to clean out the slide channels. I guess my original cleaning sessions were not thorough enough to get all the old lube out.
