(how to repair rusty garage door bottom)?
车库门底开始有点生锈。 找了一个paint contractor. 他用沙纸除锈后,用下面的漆
CIL Semi-gloss exterior paint 96604, white base, color No. 17, 100% acrylic paint + primer.

这才10多天,好像锈又开始从漆下面冒出来了。 想自己查找一下车库门底开始有点生锈应该如何修理。
刚找到两点:
1. Need to do a thorough rust removal. Sand paper may not be good enough. White vinegar may help ().
2. should use old-based rust paint such as TREMCLAD rust paint for any paint over metal, not water-based acrylic paint.

也请有过库门底生锈和修复经验的朋友一起探讨, 分享经验。
也请真会修理库门底生锈和油漆的contractor留下练系方式,以便大家能找到好的contractor。
 
正在考虑去到底下两厘米漆, 除锈, 上防锈漆,在上一层和上面一样的acrylic paint + primer.
 
自己在底下两厘米又上了同样颜色的防锈漆 (brand: TREMCLAD).

请contractor 加了一个 aluminum retainer and a new weather seal.
It was said that this will last 10 year without worrying rust.
