The instructions say: "Apply five drops of the odorless thinner to a sponge in a 5-dot pattern like you would see on the face of playing dice. The 5-dot pattern makes it easy for the paint to transfer from the sponge to the vinyl."  

The easiest way to have total control over how much odorless thinner you use is with our new Droplet Bottle for Odorless Thinner. It’s perfect for applying just exactly the right droplet size of odorless thinner to the sponge.

You can also use the droplet bottle for adding a few drops of thinner to your paint brush for quick and easy cleaning.

Odorless thinner is best used when measured in exacting amounts. The droplet bottle is the best tool we’ve found for this step.
