It would be easy to determine by taking a piece of the film leader and looking at it. Rem-Jet would be a definite black. I've processed such film and waited until the end of processing to remove the coating using a sponge. The coating material decomposes in alkaline solutions leaving only finely divided carbon. The is nothing to gum up tanks or reels just wash everthing thoroughly.

Kodak PB-2 to remove Rem-Jet coating.
