Hi PainterGirl, thanks for your question. I'm sorry to hear the paint dried too quickly and left brush marks on your window molding. To fix this, I recommend applying another coat of our Urethane Alkyd paint while maintaining a wet edge to cover the brush marks. If the paint seems to be drying too fast again, you can add up to 4oz. of water per gallon to extend the working time of the paint. Customer satisfaction is important to us, and we'd like to help get your project back on track. Please feel free to reach out to us directly so we can further assist. We look forward to hearing from you! -Christina
