Probably a lifetime supply of that grease for a few guns, Damascus. Lucas products are available locally, I use the fuel system cleaner in my vehicles in the last tank of fuel prior to an oil change.
The only problem (for me, NOT you) with the non synthetic greases is performance at sub zero temps. The wide range of temp that the synthetics stay consistent at is a big plus for their use.
Ive had some trips that featured hunting in T-shirts at the beginning, and ended in the cold front that follows a winter storm in temps well below zero degrees F.
I suspect most who post here will never have a problem with lack of maintenance cleaning and lubrication of firearms. But, it is good to see what others use, and why.

Best,
Ted
