Just buy the other grease guns. Counting the one that lives in the coach and the other on the boat, I have 6 and they are all different.
The boat grease gun has special water proof grease for the winches. The others are now all loaded with Valvoline Synpower with Moly. I have a bearing on my mower that was a bad design. The manufacture even finally recommend having a spare on hand and replacing it every 50 hours (twice a season for us). Five years ago I repacked it with the above. It is still going.....
None of the guns are Chinese. I bought one and it had a toggle plate to hold the rod back to reload it. When I when to reload it, that toggle would not hold the rod. So that gun went in the recycle bin and was replaced with a Lincoln.
