I had some time to kill yesterday afternoon, so I decided to see if I could get the rim and cup of the Schilke 14A4 that I got for my Schilke B6 plated. I took it down to my friend's repair shop and got to watch him do it, which was pretty neat - it was very fast and very easy. He wiped down the mouthpiece rim and cup, (I had just cleaned and polished it that day) clipped an electrode to the shank, and with the cotton tipped "wand" (also also attached electrially to the plating unit) began to brush on the gold solution. He then dipped the rim and cup into the container of solution and also stuck the wand in the solution, near to but not touching the mouthpiece. And that was it. He then wiped it off and did it two more times to get a thicker plating, but it was that easy - it took less than 5 minutes. He offered to plate it in platinum, but I decided to stick with what I knew and stick with the gold. Does anyone here have any experience with platinum plating on mouhtpieces?
