Internal O-Ring Chain Lube After 500 Miles

So to all of the NO lube chain maintenance guys and gals: this is a brand new o-ring chain that purposefully packed the master link with the supplied grease at just over 500 miles ago.
Wonder what happened to the grease inside these sealed pins and rollers? That's right, they get hot, then cool, then get hot again. What happens to a "sealed" chambers contents when it builds pressure from heat? You would be correct if your answer included the liquid/warm grease would be pushed out each time as the air in the heated chamber expanded until no lubricant was left.
So how do you extend the life of a part that could get rid of it's own internal "sealed" lube? Super easy- lubricate it with a bearing worthy lubricant that can possibly get a little in past the "o-ring seals". Now enters PJ1 chain lube. My preference is the heavier duty Black Label for this exact example.
