Anyone use this anymore or use it for your firearms? I used to use it and I know it is still available but I don't see it much anymore. I like it when it was in a metal can with the pull top...worked will it put drops of oil exactly where you want them. I always like to put a drop of oil on the slides and feed ramps of my semi autos and the pump spray of rem oil for example is not as efficient. Any other similar products you have experience with similar?
