www.autogeek.net , very fast shipment with Standard Ground Shipping, pretty good prices too. Also try goodspeed, the guy posts on here a lot, I think they might have it, just search for the website, it is like goodspeedmotoring.com or something??? not sure.
Lexol is probably the best choice for the RSX Leather. It doesn't cause the perferated holes to turn white. It is also a pH balanced product that will do a very good job preserving your leather. We also carry it for only $8.99 for the 500ml spray bottle. http://www.goodspeedmotoring.com/catalog.php Go to the leather conditioner page.
