Hey guys, I don't really like joining in on these discussions but since I saw my name mentioned a few times I'm going to weigh in with some thoughts I've had for a while.
The medium we (my girlfriend and I) use is in fact nail polish (sorry if you've thought otherwise metalliqaz). The dip painting process can be done with any medium that contains film-forming agents and plasticizers, with nail polish and auto paint being the two most commonly available. They are essentially the same medium. The main reason we personally chose to dip was that we wanted the finish to be smooth and uniform without brush strokes or bubbles.
We've spent a long time experimenting and perfecting the process especially after the feedback from our trial sale. I want to mention also that the process is actually a lot harder than it looks. I know some of you guys have tried it and I'm sure you'll agree. One of the biggest issues is a lot of colours not working well with others because of their particular formulas and there have been so many designs we've wanted to do but unfortunately haven't worked. We throw away far more than we sell. For example the 10 Toxic Candy Canes that we sold were the result of culling the majority of a batch of 30 or so. Basically for every key that we're happy with, it takes us a few attempts to get the pattern as we like it and another few to finally produce a key without bubbles or other significant imperfections. If anyone is interested, this is a small portion of the rejected keys:

I'm really glad some of you guys like our keys. The best part for us is creating something that we're proud of and that other people enjoy too. To be honest if you actually compare the time that it takes to make a key that we're happy with and the $10 or so that we get, it's really not the most profitable venture.
Unfortunately, it's sad to see how this all has turned out. We were full of excitement at the beginning and I really think it had a lot of potential to be something new and different on Geekhack and we had so many ideas in mind. But all of a sudden they started popping up everywhere and now the whole concept is sort of tainted in a way.
