Hello ModernHomeImprovements,
Thanks for taking the time to review our Satin Enamel Interior Paint and Primer in One. I'm sorry to hear there were white specks and dust/debris in the paint, causing the spray gun to get blocked. I can assure you this isn't the experience we want any of our customers to have, and I'd like to hear more about your experience. For further assistance, please feel free to reach out directly to our customer care team. We'd love to help! Best, Roxana N.
