A couple updates on the wrist rest.
It's especially obvious from
this picture that the polycarbonate looks kind of splotchy. I believe that was exacerbated by the sandblasting, which left super fine particulate on it that soaked up oils and gave it that splotchy look. My friend had a great suggestion, which was to rub an oil over the entire polycarbonate surface to give it essentially a uniform coating. So I wiped it down with a damp rag to get rid of as much particulate as possible, and then applied a super, super thin layer of a synthetic oil. It looks amazing now -- super uniform look and barely any noticeable splotches from my palms resting on it. It also felt sort of chalky before (I think due to the fine particulate on the surface), and it doesn't feel that way now (it feels much better imo). I'll likely treat all of the polycarbonate parts this way before sending them out if/when a GB happens.
For folks asking about getting one, I'm going to hold off for a month+ for a couple of reasons. First, I want to wait long enough that folks can get one who ordered a No. 1 in the second round, and the timing on that is still a bit up in the air. Second, I want to see how the finish holds up to consistent use. The polycarbonate is sandblasted, and I expect my palms will polish it over time, which might not be a good look. I want more time to evaluate how fast that happens and explore alternatives if needed.
