Some scientific questions...

Hey all you hard workers!

I've volunteered for a STEM program this summer, and I have a very technical question. We are going to be building several standardized drone kits and using a lesson plan from a company called Flitetest.com. It's called the tiny whoop. My question is, on the standard 2x paint + primer in white, red and black, what is the weight of 1 oz. of liquid paint by weight (by weighing the can on a precision scale) after it has dried? Since this is STEM, we will be covering just about everything in the construction. We will be using this info as a variable to see how different things affect performance.
