Hi Nathan, thanks for your review. I'm sorry to hear about the clumps and lumps in the container you used. To fix this, I recommend stirring the paint for 5-7 minutes to resolve the clumps. And if there are dried clumps on your project, you can sand these smooth, clean off the sanding dust, and touch up if needed. Customer satisfaction is very important to us, so feel free to reach out to our Customer Care team directly for further assistance. They are always happy to help. Enjoy the rest of your day. -Christina
