will it never stop
No, it will not. For example, over a period of many many years I tried and used a wide assortment of patch lubes, both commercial and home made. About three or four years ago I finally settled on straight olive oil as being as good as any and better than most and started using olive oil exclusively. Then last year I tried Liquid Wrench on a lark. Now that's all I use. Next year I may find that used motor oil from a Chevy engine with at least 80,000 miles is the best patch lube ever.
