I was SO friggin frustrated with this product when I started using it, my question for you is this, Did you dilute it? I had the same issues with my application, darker streaking all over, made me crazy!! I corrected it by diluting it 60-reload/40-water and my streaking problems were gone and now I LOVE this stuff!! You will need to re apply to correct streaking. But using a good microfiber (haven't tried damp) and the proper dilution for darker cars and you too will love it! Good luck, let us know how it goes!
