Unverified判断真正防水看接缝工艺：车缝线针孔本身会渗水，只有做了压胶条（贴条）密封的接缝才能真正防止大雨渗漏，普通车缝未贴条的号称防水实为泼水88% similarUnverified标称耐水压需结合接缝处理判断：涂层达标但接缝未压胶或未涂密封胶时，缝线针孔仍会渗水，是天幕实际漏水最常见原因87% similarUnverified判断防水缝线工艺：翻到内侧看接缝处是否有压胶条（seam-taped），无压胶条的车缝线针孔本身就是渗水点，长时间淋雨必湿86% similarUnverified防水帽的接缝处是渗水薄弱点，选购认准车缝线做了压胶密封（seam-sealed）的款式，无密封处理的普通缝线在暴雨下会沿针孔渗漏85% similar
