How do I mix this?

I need to mix some SS paint with mixing ratio of 8:1:2............. I have a universal mixing cup with 8:1:1 and that lest # 2 throws me of, how much do I put to equal 2. The mixing product order would be 8 parts of paint, 1 part of reducer and 2 parts of activator (hardener) is that correct?

Thanks in advance.
 
As long as you have the correct amounts the 8 parts paint:1 part activator:2 parts reducer, order added is somewhat irrelevant, as long as it all gets mixed in and in the correct amount. If your cup doesn't have an 8:2:1 scale, then use ounces marks.add 8 oz, then add another 1 oz, then add the last 2 oz.(8 oz mark for color, 9oz mark for activator, and 11 oz mark for reducer, or 16,18,22, etc) Or make marks on a mixing stick at a measured line (IE every 1/4" or 1/2" whatever works best for your application and amount needed), just be sure you have a flat bottom can with vertical sides (IE metal paint can) your mix will be off if using a tapered type cup. You could also use the 8:2:1 scale on the cup if it has that and just make sure you are adding the reducer at 2 parts, then the activator at 1 part. Several ways to do it and I am sure some others that I have over looked. Also, if you have a tech sheet for the paint make sure what products are used at what amount, usually will tell somewhere on the label as well (IE 8:1:2, the 8 is color, the 1 is likely the activator, and the 2 is likely reducer, but make sure that is correct for your particular paint.) Sorry if I made that a lot more complicated than it needed to be.

Normally the 2nd number is activator but I have seen a few enamels over the years where that was not true, so you may want to check the tech sheet or with store because at that ratio, used in wrong place could cause problems.
 
If that 8:2:1 ratio is correct, it can also be read as 4:1:0.5, which is also the same as 4:1 plus 10% reducer. Most mixing cups can handle that.
 
Thanks guys for your help, Berry you were correct the mixing ratio is different, its 8:1:2, 8 parts paint,1 part activator and 2 parts of reducer. I think the ounces scale will work the best since I cant find a mixing cup with 8:1:2 mixing ratio.
 
I won't knock it, but I will say that most of us have moved on to more durable paint technologies. Nice thing about acrylic enamel is it's a bit more forgiving than today's high solids polyurethanes. Hope it works out well!
 
You're right crash, I do need to catchup with today's paint technologies its a learning cure for me. I need to spray some wheel rims inside and outside, I'm hoping its though enough to out-stand tire mounting without chipping all to hell. If it does not work no big loss its only a quart, just a lot of work striping all down and starting from scratch.
 
It should be good for wheels, especially if you have decent primer on them. It's top surfaces like hoods and roofs that will fail first with A.E.
