摘要： A method for repairing a scratch in the clear top coat overlying a pigmented base coat on a metallic substrate, without damaging the pigmented base coat, involves the steps of applying an amount of a repair composition to the scratch at least sufficient to fill the scratch, spreading the composition into and over the scratch until the composition at least fills the scratch, removing excess composition, allowing the composition to air dry, sanding the dried composition to create a smooth, continuous surface at the site of the scratch and buffing the sanded surface with a fine polishing compound to establish a high gloss, clear coat surface at the site of the scratch. A desirable resin composition consists essentially of, in percent by weight of the composition, toluene 10-18%, n-butyl acetate 10-15%, ethyl acetate 0-5%, acetone 20-25%, acrylic resins 30-50%, surface tension reducer 0-0.5% and plasticizer/coalescent 0-3%.

摘要翻译： 修复覆盖金属基底上的着色底涂层的透明顶涂层中的划痕而不损害着色底涂层的方法包括以下步骤：将至少足以填充划痕的一定量的修复组合物施加到划痕上， 将组合物铺展到划痕中并在其上方，直到组合物至少填充划痕，除去多余的组合物，允许组合物空气干燥，对干燥的组合物进行砂磨，以在划痕部位产生光滑的连续表面并抛光砂光表面 用精细的抛光化合物在划痕部位建立高光泽，透明的涂层表面。 理想的树脂组合物基本上由组合物的重量百分比组成，甲苯10-18％，乙酸正丁酯10-15％，乙酸乙酯0-5％，丙酮20-25％，丙烯酸树脂30-50％ ，表面张力减少剂0-0.5％，增塑剂/聚结剂0-3％。
