Designed with standard hardness, it provides a dependable balance between durability and sandability for everyday seam filling and surface refinement tasks. The superfine texture spreads smoothly across joints and imperfections, curing without shrinkage to maintain consistent surface alignment. Once dry, the material can be sanded and shaped to prepare parts for primer and paint. Because it is polyurethane water-based, the formula produces minimal odor and can be cleaned from tools using water prior to full cure. 📐 Specifications Brand: AK Interactive Product Type: Acrylic modeling putty SKU: AK-104 UPC: 8436564920683 Volume: 20ml Weight: 39g Base: Water-based polyurethane Cleanup: Water (before curing)
