I've used my ICP42 roller transport with Ilfochrome for over 15 years and never had any erosion of the rubber rollers. Now I'm doing the Kodak RA4/RT chems. I've tried 2 configs and both cause little pits in the last tanks roller.
The first config was DEV, then BLX/FX, with water in the last tank. The current config is DEV, stop bath, with BLX/FX in the last tank. The chems were only in the machine for about 7 days. These little pits are only going to get worst and I can't easily find replacement rollers.
