I buy cheap old brushes at Walmart or other places and throw them away. I also get some craft sticks...which are like tongue depressors...at walmart. For small mixing containers I use paper cups, or small plastic cups bought at HEB. For some little bigger mixing cups I use "I can't believe it's not butter" plastic containers, or similiar ice cream containers. My mixing sticks are about 3/32 X 3/4 ripped out of an old board and cut to length. For sgueegees I use heavy card stock cut about 4" X 4" and throw it away after use. I use disposable plastic gloves. I just can't believe I'm spending any more than $10 for all this peripheral equipment. A miniscule amount considering the overall cost. I also save all my sanding dust for wood flour.
