So I live in a humid environment (SC) and started noticing some severe spotting everywhere my car has PPF installed. At first I assumed these were water spots from rain or maybe tar although I couldn't recall driving through any construction sites. So I bought some CHemical guys water spot removal and it didn't even touch this stuff. I'm starting to fear that some way some how this is actually mold under the film although I've never even heard of that. I've had the car roughly 2 years and it was 2 owners ago when this film was installed. Am I SoL as far as any method to get this stuff out? The work was done in Kentucky so even if they were to honor some form of warranty I doubt its worth the drive. Pics attached.
