mixing primer with paint

I have a huge bucket of primer and want to use it to lighten the color of a gallon of paint I have. Can you mix paint with primer and use as a finished coat?

It usually won't work.
Primer is generally flat, and if your paint has any sheen to it, it won't fly.
Pimer will create a surface entirely unable to be washed, as compared to finish paint.
To get technical, primer/paint employ different types resins, solids, and hardeners from each other. Play chemist, and who knows what you will end up with.

Not only that, but it takes a LOT of white to lighten color.
A pint of color paint to a gallon of white will only lighten the color a shade or two.
Save the primer. You will have lots of projects that will need primer.

The zinnzer 123 has a satin finish sheen to it. Is it interior or exterior paint? Flat or satin or semigloss? What color are you trying to lighten, a deep base or mid base or light? You can always play around with mixing paints that thin with the same material (oil, or water). But for best results as, it is your time, getting the color you want will give the best results. Tinting with the primer and getting a color you like and then haveing it made to match your swatch gets you what you like without guessing and having stuff mixed from color chips.

Jeffk - for best results, follow PWGs advice and don't mix primer and paint. There is a greater chemical difference than just the sheen.
