| Dave your seats aren't coated by your description. Its uncommon for that vintage leather to be clear-coated. On the other hand, it may be pigmented leather like my Alfa, which has a thick layer of pigment over the top - that can be water-resistant but over time the pigment crack and allows the use of real leather conditioners. RO is the right way to go.
If the Lexol/TW has a silicone content (designed to seal the leather, like vinyl dressings) then that will effect absorption, by making it somewhat water-resistant. I think they do contain silicone.
The longer its left in the heat, the better. If its still not absorbed I'd leave it another day or so. In case the previous dressing is interfering with the absorption, I'd try scrubbibg the surface with a nail-brush (while the RO is on it) to try and break up the possible silicone surface. It could also have have absorbed a buildup of silicone from applications over the years.
If, after the nail brush, the heat, and 48hrs, it still hasn't absorbed, it means that either your leather is in great shape, or something is interfering with it. Wipe the residue off with PC, and try again in two months.
