Check out the hospital pharmacies and schmooze. I send Rikki in and hover outside since one look at my mug and I'm given the bum's rush. Rikki just picks a guy, giggles and "chat's them up" and comes out with a bag full.

One thing I found that helps is to pre-warm the hardener and resin in a tub of hot water.

Another nifty thing is the clear Dixie plastic measuring cups. A bag of 50 costs about $4-5.
