I was using OrangeSeal, I can tell because of all the orange streaking on the sidewalls..
The weeping seems to be pretty random. I have a buddy who had one tire weep, and one tire not.. he got a replacement and it was 50% better.. but still not as good as the non-weeping tire.
Of course, none of these tires have a sealing "butyl layer" like a true Tubeless Ready tire (and the associated +100 grams and extra rolling resistance) so I don't really have a legitimate complaint.
