I thought that too with some spots. When the light hits it plays somewhat. After inspection in the light, there is a spot near the front driver side headlight and an other near the passenger side. So, I will have to shoot again, but that I figured on. I'm still cleaning up. The air hose was new, but now coated with copper and it has a maple syrup feel. The compressor too' got over spray on it. I borrowed the compressor, so it needs to be cleaner than I got it. On the funny side, as I cleaned the measuring cup that I used to add the thinner, I erased the writing on the side of the cup. It was a dollar store cheap plastic one, so I'll just toss it.
