Well pretty much the thing about critically taped seams is this: when the manufacturers waterproof tape the seams they do two possible things. they either a) critically tape it, where they just tape the parts where they THINK water will leak in. OR b) FULLY TAPE the seams so they get every nook and cranny. critically taped seams leak like a bitchhh from past experience so fully taped ones are the way to go cus the water NEVER EVER gets in. cus you know...well there fully taped. everything is taped up so nothing gets in.
