From everything I've read, that is NOT the calcium-based Lubriplate we should be looking for. The correct stuff comes in a tube with a completely different label.
'Calcium based'? The low-temp grease tube says right on the label that it's 'petroleum oil.'
And who is 'we'?
By the way, I have both makes of the Lubriplate. The 'regular' Lubriplate grease, which I've used for at least two decades on my M1s, is white. The low-temp stuff is gray-ish in color.
