With the shutter set to Bulb and f/3.5, using the shutter release lock, with a little care you may also clean the front surface of the rear group through the shutter without having to extract the rear mount from the shutter also. Otherwise it sounds like you now have a great 3.5F for a bargain price overall—although I don't think the repair costs were a bargain by any stretch of the imagination...
There aren't any notches in the front ring but I've used a rubber stopper before to remove the cells. Once I get them out I shouldn't have any problem removing the front element and cleaning it. I've done this on a Xenar Rolleicord and not too worried about doing it on the Planar. If I need to I can send it to Paul Ebel.
I felt the price was good if they'd done what they were asked to do but for what they actually did it was a ripoff.
