@avpato: If you're getting contamination on almost every install, it's probably not the film. Here's what I'd check first: - Spray the air before peeling the liner. - Stop using tap water and switch to distilled water. - Clean your spray bottles regularly. - Use tint gel around the edges. - Most importantly, master the basics before buying more tools. Great tools can improve your workflow, but they'll never replace proper prep. #windowtint #SmallBusiness #entrepreneur
