Hi Tmw74- Thank you for your review. I'm sorry to hear about the debris in your paint, the lack of coverage you got with one of the gallons, and the brush marks! Our Marquee paint should not have an splinters or other debris in the can, and I'm concerned that this was the case for both cans you purchased. This product is also guaranteed to cover your previously painted or primed surfaces in one coat when tinted to a color from our One-Coat Color Collection. Colors outside of this collection may require additional coats for full coverage. To fix the finish, I recommend lightly sanding down the unwanted texture on your walls, wiping the surface down to remove the sanding dust, then touching up with more paint. We'd like to assist you with this further. Please feel free to reach out to us directly at your convenience. We hope to hear from you! - Sara
