近几年,新造的现代化客车客室宽敞、明亮。但1945年以后生产的客车,客室内的油漆漆膜发黑,起泡,龟裂和剥离。现在,维修这类年久老化的客车,仅在老化的漆膜上重新涂上近年来研制的涂料,以使客室内明亮化。但是,这种清洗重涂的方法并不能恢复美观。欲显出木纹的美观,必须把老化的漆膜从基体上剥离掉,直接在木纹上重漆。另外,用彩色进行补漆时,须用油腻子填补破裂、剥落之处,采取使漆膜表面光滑的补涂办法。可是考虑车辆的使用年限,如表1所示,用上述的方法从经费和工期两方面加以比

However, since 1945 after the production of passenger cars, passenger room interior paint film black, blistering, cracking and peeling.
