ok I admit that I am stupid.

Fwiw, I've been using a glass Pyrex 3 cup measuring cup.

I figured first time I cleaned it up with lacquer thinner the red letters and numbers would vanish.
Didn't phase em.

I've mixed acrylic enamel, epoxy primers, acrylic lacquer, catalyzed enamels and so far so good.

The cup is a garage cup though and hasn't seen the kitchen since it came out to live in the paint cupboard....

:LOL: you guys make my day.

PPG makes a paint stick with Graduated numbers all in exact increments .

fill empty clean can with color to the 8 ( 8 parts color ) , then pour reducer to the 10 mark ( 2 parts reducer ) then pour hardner to 11 ( 1 part hardner ) & stir :)

thanks spraytech. i will try to find one.

Barb you are at least six months to a year ahead of me on your project ( truthfully a lot more!) so I'm quietly sitting back and learning with you!:)
