I will just try but not the expert here. All your colors will look different when applied and some like white or pearl base coat. Some times I apply 2 coats of color to make darker. Less coats you can do are better on jigs as it can get a little thick. I use a small propane torch. One bottle will last several years as I do not do that many jigs. I would say about 3/4 full. I will leave the blue question alone as that is in the eye of the beholder and what your looking for. Experiment. You are going to paint jigs you don't care and some you love. That's just how it works. You are going to do fine and follow this thread a while, there are some real experts here at CDC that will have great info
