I'm reaching out to clarify whether your paints are suitable for use on glass and outdoor surfaces. It's important for us to ensure that the products we choose can withstand various environmental conditions and adhere effectively to different materials. Additionally, if your paints can indeed be used on these surfaces, I would love to know if there are any specific preparations or application methods recommended for optimal results. Understanding these details will help us make an informed decision in our procurement process. Looking forward to your insights!
