The key to having zero leakage is very simple, properly match the cap and bottle. If a chain lube maker's bottles leak, it's simply because they've chosen bottle and caps, which aren't correctly matched, probably because they shopped by price rather than quality.
Of course, any bottle full of liquid may leak, but it should only be in rare, isolated cases.
Very nicely pedantic post. So what's you're assessment of the OP's problem? Did ProLink choose the wrong caps for the bottles he got that leak and the correct caps for the bottles you got that didn't? Or is he simply very unlucky and against the odds got multiple isolated bottles that leak?
And, in your esteemed estimation, what would his best course of action be, just buy new bottles of ProLink and expect (hope) they don't leak?
