DIY Diamond Spray solution for strops.

My solution was
3 oz distilled water
2 oz of humidor solution (50/50 water /propylene glycol)
25 CW = 5 grams monocrystalline diamond powder.

With this solution I still get settling but not as fast as straight water.

I use my diamond spray solution on 1x42 leather belt and a flathone scissor honing pad. When using the solution on the flathone for hair shears on a felt pad, the scissors would get hot enough that the propylene glycol would crystalize and form a hard shell on the metal. My last batch I have changed my recipe to the following:

2.5 oz distilled water
2.5 oz of Di-Propylene Glycol
3-5 cc of Camellia oil
25 CW = 5 grams monocrystalline diamond powder.

So far this is working extremely well. I notice the solution is keeping the diamond powder in suspension much, much better. It spays out on my work surface as almost a sort of light thin foamy appearance. Maybe I should have use 3oz water to 2 part Di-Dropylene Glycol. But it is definitely better than using the propylene glycol product.
