Proper wire bar for drawdown of low viscosity coating, or other tools needed?

Proper wire bar for drawdown of low viscosity coating, or other tools needed?

(OP)
Hi,
We use coating in our daily production. We prepare the coating our self by mix 10% of pasta/ toner, 45% of acrylic, 45% of solvent and stir them for 3 hours by using electric agitator.
The mixing result will be a low viscosity coating (flow rate of 25~35s, zahn cup no 2 at 25C).

We need to check color consistency from batch to batch of mixing, prefer a quick drawdown method.
We have tested the drawdown using 44mils wire rod and 26mils wire rod but the result, the coating film is way too transparent and
we can not see whether there is a color different or not. Is this the best inspection method of color consistency for the coating that we use? Should we use the bigger wire rod or other tools needed?
please advise.
