Hi Frrd, thanks for your review. I'm sorry to hear you didn't get the coverage you expected and that the door is sticking. Our Marquee Paint should cover in one coat when applied over a previously painted surface and tinted to one of our One-Coat Colors. This paint should cure and harden in about 4 weeks; however, please keep in mind that darker colors can take more time to dry. Ensuring our customers are happy is our top priority, and we are eager to help get your project back on track. Please feel free to reach out to us directly for any additional support. We look forward to hearing from you! -Christina
