RC is reputed to be archival but if I want to feel secure I will use the Fibre with a KRST soak. I use the RC for "give-away" and build my collection with FB.
Kodak used to make a Polymax RC paper as well, but I think it was recently discontinued. It printed very differently from Polymax Fine Art, which is Fiber based. The Kodak RC papers are junk in my opinion, especially compared to the Ilford RC papers. My major problem with them is that there tends to be a milky haze over the whole image, as well as a metalic reflectance from side angles. The PolyMax Fine Art (FB) has none of these problems and is a very nice paper with the right image.
