I'm reaching out to inquire about your silicone sealant, specifically the weatherproof variant, as I'm looking to procure a wholesale quantity of 789 units. Before proceeding, I would appreciate if you could provide some details regarding pricing, available colors, and any relevant certifications or specifications that might help in making the purchase decision. Additionally, it would be great to know about your production lead times and shipping options so I can plan accordingly. If you have any bulk discounts or promotions, please share those as well. Looking forward to your prompt response as I am keen to establish a partnership for future orders too!
