Hello, thank you for your review. I'm so sorry to hear about the trouble you had with our Marquee Paint, especially compared to your previous positive experiences with our paint. That is not typical, and I can understand your disappointment. Our Marquee Paint should cover in one coat when tinted to a One-Coat Color and applied over a previously coated surface. To fix the streaks, I recommend letting the paint dry for 24 hours so it can even out and allow you to decide whether another coat is necessary. If needed, with the number of coats you have applied, recoating the surface will provide the proper uniformity. Your satisfaction is important to us, and we want to help turn this around. Please reach out to us directly so we can learn more about your project and assist. We look forward to hearing from you! -Lina
