Thanks! Yes I have brushed Oysterflex end links before. A steady hand and a guide to keep the sanding block straight made it easy.If you don't like it you can easily brush the mid link, believe me (it was the first time for me) the polished part came off like a butter with scotch brite, you just have to be careful to make fairly straight and fast movements, maybe do some tests on a cheap bracelet before...
I am really interested to see how PCLs look on my 5 digit watches! This thing is in the mail!!!
