I don't know anything about old tires but I can confirm that the tires pog and grug use puncture super easily. It's the pursuit of low rolling resistance. I read on bicyclerollingresistance that reduction in casing thickness leads to the gp 5k S TR having 30% less puncture resistance than the previous gp 5k TL, the manufacturers across the board bank on sealant saving the day but obviously that is not happening.
Never happened for me either because it seals but only after the tire is flat or near flat
