i basically used both capecod cloth and a jeweller's polishing cloth. cape cod the whole case a few times (i did that twice) to remove the top, rough layer of PVD coat to smooth out the finish. wash it w detergent and polish again with the jeweller's cloth. then capecod the whole case but pay particular attention to the edges of the case to take out more pvd from the edges to give it the well handled look. the uneveness of the pvd coating will result in some spots getting polished to a lighter colour, giving the patina.
the pvd on the crown is really thick! i'm still trying to get it to look used..
the first batch of DSN's pvd is great!! subsequently he changed the CG to a bigger one which imho is nt accurate for the a/b series.
