Amazingly I use an almost identical method to C Senor.
As I work my buffing micro fibre gets too damp to buff and becomes my drying micro fibre and I get a new one out for buffing.
Did one as my first clean just like this today, she was amazed with the results when she got home. A very happy customer.
I actually charge em 40% more for leaded, not sure if this works out in my favour or theirs, but I do tell them that "I can not squeegie them so it takes longer as I have to buff them by hand but it does give a very nice finish"
I think C Senor feels thinks the same as me, doing leaded can look amazing, and it feels very satisfying even when the insides are dirty. I quite like em. (but will always charge extra for em)
I do not like scrim, but that is due to my inexperience I think.
