I wish I knew about these paints you were talking about, are they specifically made for clay? Or something that can be used on a variety of surfaces like canvas and walls or paper?
None of them are made specifically for polymer clay - polymer is just so manipulatable (I made up a word, hooray!) you can use practically ANYTHING on it once it is baked (and in the case of alcohol ink, unbaked too!).
You can get almost everything I mentioned from Micheal's or other big craft store. Alcohol inks and chalk inks are in the stamping section, as is the pigment powder. Rub n Buff can be found in the gold leafing section (but not in all the available colors - I went to http://www.dickblick.com/
for a few colors I knew I wanted and Micheal's did not carry). Acrylics are just in the paint section.
Gilders Paste was a little harder to find, I had to get it online - I got it from Lima Beads (http://www.limabeads.com
), but there are loads of places online to get it. Normally, it is used to color metals I think. Also
at you for making me look that up - I forgot how many colors I DIDN'T get 'cos I wanted to try it out first, and now that I have I am hooked and now I have to wait 'til payday so I can get more. hehe
