Paint Mixing for Idiots

[Chaparralman1974]

Ok, I am going to apologize in advance for a dumb question....but math was never a strong point with me, so please be gentle. :-)

I am getting ready to apply a seal coat of epoxy primer to my project. I am using the eastwood epoxy primer which is a 1:1 mix ratio of primer to activator.....easy enough. Now, according Eastwood, I need to reduce this by 20% with a urethane reducer in order to use it as a seal coat. How do I do this on a mixing cup? I have a boat load of these.

Math sucks....plain and simple. In high school I dropped out of geometry because it was dumb and I would never ever need to know squat about angles. Well, I ended up joining the Marines and they made me a mortarman.....I guess Mr. Tuttle (geometry dick in HS) was right after all.
