In the 70s I had to deal with the "REM-jet" backing just as Jeffrey describes when processing Ektachrome Super 8 film in the old E-4 kits. Never had that problem when doing Kodachrome in B/W Reversal chemistry. Kodachrome processed not that different from Plus-X Reversal as I recall. But that was 35 years ago using orange dichromate bleach (most b/w reversal kits now use the purple permanganate bleach). Can't say for sure what the results now would be.
