I wrote off for the free sample on their website and it arrive today with some pamphlets on just how good it is. (Usual advertising propaganda). Anyways, will try some out on the Gamo first. Apparantly it provides a non-stick non-dust kinda film on the metal. Will see how good it is.
I received two 0.5 fluid ounce squeeze tubes. One is a grease, the other appears to be an oil.
No idea what a fluid ounce is, but it looks about 4 teaspoons full.
If anyone else want's some just go check out the website.
The free sample is somewhere on the site. I remember I struggled to find it.
