I use a synthetic lube that is compatible with the seals, the last lot was made by Kleen-flo, and I use damn little of it - just enough to let the pistons slide in easily. I also tend to bed the dust seals in a light coat of it to help keep the road salt from getting into the grooves. Methinks that's not such a problem for you.
Why replace the seals unless they were leaking? Cleaning the pistons before stuffing them in past the seals for new pad clearance I can understand. Keeping fresh (and dry) fluid in the system is also a good thing. Having brake fluid anywhere outside of the bore seal is a bad thing because it absorbs water and causes corrosion - yet all old-school books claim you must use clean brake fluid as a "lubricant". Not in my shop and cars!
Just did the same two weeks ago on my 944 N/A. Quite different as it is a single piston with a dust boot. Also a nice and rewarding job to do!
What do you recommend is the best way of bleeding the brakes? Old school two persons with one person operating the brake pedal en one person releasing fluid/air until there is no more air coming from the caliper. Or do you use some air pressurized tool?

I use rubbing compund to remove the black stuff on the piston.

Like your technical video's a lot!
