This idea of needing some type of "rim lube" seems nuts, to me. I've mounted a lot of tires in my day, and if I inspect the seating after inflating it for the first time and find an area that isn't quite perfectly seated, I just say "Oops" and then deflate the tire, fix the problem with my hands (it usually only involves an upward push with your thumbs), and reinflate. Getting the tires over the rim is sometimes a challenge, but getting it seated evenly is not. Deflate, Adjust, Reinflate. Simple, and nothing needs to be applied to the rims.
