Tips Help Ease Project Car Work Paint
Figure out what the mix ratio is. It will either be on the label or on the techsheet available from the paint supply store. In the case of this single-stage enamel, the ratio is 8:1, meaning one part of activator (also referred to as hardener) gets added to eight parts of paint.

Find the corresponding mix ratio scale on the mixing cup. It's printed forward and backward because some guys like to look through the outside of the cup as they pour the paint. Notice there are three columns. Some paint formulas have a third component, possibly a reducer or a custom effect like a candy or pearl, in addition to the paint base and activator. If that were the case, the mix ratio may read 8:1:1, that is eight parts paint, one part activator, and one part thinner. In our case, though, we only have to mix two components to an 8:1 ratio, so we can ignore the third column.

Next, figure out how much paint you want to mix. Generally, you should mix as much as the paint cup on your gun will hold, unless you're spraying a small part. Place the mixing cup on a flat surface with the proper mixing ratio scale facing you and pour the paint.

Note that the numbers are staggered, column to column, according to the ratio indicated at the top of the chart. So if you pour the paint to the line marked 1 in the first column of the 8:1:1 section, you only need to add enough of the second component (the activator, in our case) to bring the level up to the 1 mark in the second column in the 8:1:1 chart. If we had a third component to add, we'd just pour until it reached 1 in the third column. That's all there is to it-the cup has the ratios figured out, so you don't have to do any math.

Our paint label suggests we reduce the mixture 10 to 15 percent prior to spraying. Reducer is just a fancy name for paint thinner. It makes the paint flow more freely through a spray gun. Some paints do need thinning, too. Paint that's too thick will come out in globs and won't level out on the surface. If we were real geeks, we'd have figured out the volume in our paint cup and taken 10 percent of that. We then would have added that amount of reducer to the mix. Honestly, though, we just guesstimated it. You can tell after a while what the best viscosity is by watching how the paint runs off the stir stick. Paint should be slightly thicker than the consistency of water.
