Nason Full-Thane lists the ratio as 8:1:2
My mix cups have 8:1:1
Using the '5' scale the distance between the 1:1 is 3/8".
Will adding 3/8" mark to the last column give me an 8:1:2 ratio?

To end confusion pour your thinner first.
8=paint
1= Hardner
2=reducing agent.


Or- use another cup and pour out your reducing agent or thinner using 2 of the 1 column
 
Isn't the cup getting wider as it fills up? I would think if the distance between 1:1 is 3/8, then the distance between 1 and the new mark would have to be a tad less because of the wider top part of the cup?

You are correct in your calculation, but this is the reducer, a skosh more won't hurt. The paint is a very light metallic, Medium Brown Iridescent, so a bit thinner will work fine.
I can work it out in mm and ml if you prefer....
I'd also need a much finer Sharpie, and possibly new glasses! :rolleyes:

Should be good. But, don't over think it. The reducer ratio does not need to be exact. Not like the paint:activator ratio.

Agreed.
 
I’m guessing SS Nason? Don’t get it too thin it won’t cover well. It doesn’t have the best solids in it. That’s why it’s cheaper than others. My 2 cents. Craig

Thanks, I'll keep it on the lighter side of the mark and see how it sprays. Easier to add reducer at that point.

No worries. I thought that you were inquiring about your measuring logic. I am not sure how paint chemicals interact so I try to follow the instructions to the Tee......Which we all know is not carved in stone.:)
