不论什么样的汽车都会有或大或小的伤痕，有的是刮到了路旁的花木，有的是不知道谁家的熊孩子干的坏事。究竟伤痕对表漆造成多大的损伤？怎样才能修补？对于车身的老化、伤痕的检查保养，都必须考虑正确的处置方法。处理不当，不仅起不到修复的作用，反而会使情况加剧，如果是不太醒目的伤痕，聪明的方法是倒不如不要去管它。

对于较深的伤痕，重点是观察金属面是否露出，如果看不到金属面就不会生锈，可以专心地涂上修饰漆。用笔尖一点一点地点上去，然后等漆完全干。很深但细长的伤痕，用彩色油灰可以修补得很好。伤痕处用砂纸，不要随便将伤痕面扩大，重要的是将脏污清除干净。油灰要仔细地涂抹，使之完全进入内部。最后涂上混合剂、上蜡，结束工作。

凹陷处理是车身保养中最麻烦的工作之一，重要的是打好底子，若这个步骤做不好，涂装做得再好效果都不佳。喷漆时，不要忘记用报纸遮好四周，使涂料不要向周围扩散。

汽车防锈方面，如果发现生锈后，立即着手解决，如果放任不管，锈点就会慢慢扩大。防止生锈的方法是用砂纸擦净，或用使锈点变化的化学合成剂。根据情况不同，分别使用。

 车门、行李箱周围粘贴的防水胶条容易剥落、扭曲。但如果没有破裂、变形，可以再一次使用，只需将它重新粘贴，就可以防止漏水。用保护剂恢复橡胶本身的弹力也很重要。

保险扛的伤痕处理方法是将毛刺削去，坑洼部分涂上油灰使之平滑。专用油灰，准备各种颜色，选择最接近的颜色。与车身同色的保险杠，喷漆很重要。

了解了这些划痕修复的方法之后，我们可以以此来判断一些车身是否经过修复，尤其是在选购二手车的时候，掌握一些简单的检测方法能尽量避免被卖家忽悠，做出自己的判断！
