有人说车行做一次一百左右，有人说Walmart做一次五十，有人说加拿大轮胎还卖涂料可以自己搞，有人说新车如果让dealer作分高中低档，价格为700，500，300，还有人说美系车出厂自带防锈，只有日系车要自己做，有人说每年都要做，有人说做一次管十年或更长，有人说防锈涂料是沥青，有人说是别的东西，还有人说只有东部需要做因为洒盐比较多... ...

有没有个权威一点的答案？谁知道？谢谢！

网上找的帖子，不知有没有权威性。

My dad is a retired chemical engineer and often went up to northern Alberta to look at the oil pipelines. The pipelines are above ground and are exposed to year round weather, so they needed to ensure that the pipes did not rust apart and explode oil in the middle of nowhere. What they did is attach zinc rivets along the pipeline. The zinc becomes a sacrafical ion and rusts away first leaving the other metal clean of rust. When the rivet nears the end of its usefullness it gets replaced with a new rivet.

About 10 years ago I was talking to a mechanic about this and he told me that his mechanics instructor had a truck from the '40's or '50's that had the original body and no rust. The instructor bought the truck new and attached zinc rivets to the body under the vehical where they couldn't be seen. Apparently the truck never rusted.

Using zinc as rust protection isn't a new idea and is used widely in the auto manufacturing of new cars. I "think" that the amount of zinc used to protect new cars is so minimal that it has a limited life span. Also, it is pretty hard to remove your body panels and respray them with more zinc, whereas the zinc rivets can easily be replaced.

I suppose you have to ask yourself how long this car will last. Sure you can keep the body clean from rust for 30+ years, but what about the rest of it? My buddy in Waterloo just sent his 1990 Civic to the wreckers last week due to rust. The body didn't rust away, but the power steering lines did and to replace the lines would have cost $1500+ or triple the worth of the car. My '98 Civic only has rust spots on the hood where stones were kicked up and took off the paint. Protect the nose of the car and it should be fine.

So I suppose I am saying either do it the right way with zinc rivets or don't worry about it and enjoy your car for at least 10 years.

美系车绝对不会自带的，胡传。
因为美国冰天雪地的地方并不多，增加这个成本简直是胡闹。
价钱确实是不等，有年长的还有一年期的，一年期的也就50，100，每年都得做，可想效果怎么样。
材料基本上就是一种类沥青的橡胶涂层，至今我还没听说过有零售这种材料的，那些自己弄得仁兄们肯定是找相似化学材料搞得，其实就那么个东西，在好端端的铁上面喷上一层橡胶，仅此。

建议：买新车，开上路之前最好就做了。像我的车就做过了，防锈措施带终身质保。定价1000块钱打7折做的。


买二手车的，如果不是极度爱车，并且又是老爷车，不做无所谓。

做这个的无非就是想把车留在自己手里一辈子的人，和劳动强度高的车比如皮卡，铲雪的，特殊单位的。
将来打算卖的，买来就是二手的等等，没意义，因为钢铁没那么娇气。
