Wow! Quite the collection there. I had read that Chamois worked real good. Only problem, I didn't know where to get a "real" chamois cloth. I poured my powder back into the cup it came in. Wasted some too. The test cap would surely be better if our humidity doesn't make it clump up. Where's the cheapest place to buy powder? Also what glue did you use to keep the chamois on?
