Don't forget to think about wheat flour. 5 lb. is US $1.75. The
missus probably has some older stuff perhaps so make a test. I mix up
my 2:1 expoy to make three ounces, and found that 2/3 Cup bread flour
makes a very thick putty. It does not finish smooth, but very rough.
A thinner mix will flow some. Also it mixes in the epoxy much better
than talc.

I pay US $5 for a 1 lb. can of talc or micro baloons.
