Hi everyone,

I made an appointment to rustproof my 1998 Metro. The body shop said they will pressure wash it, remove any existing rust on the undercarriage, and then apply a black anti-rust chemical (forgot the name). Is this a good idea, or should I do something else? I just want to do a bit of preventative maintenance here, since you guys have convinced me rust is an issue with these Metros.
Thanks.

Is it a rubberized undercoating or is it an oil-type product? I would recommend against rubber undercoat unless the car is brand new, has no rust at all, and is perfectly clean underneath. And even then, I'd go with an oil product if available.

An oil product will have to be re-applied every year, but it's more effective since it creeps into all crevices and seams. A good rustproofing should include spraying inside cavities (especially rockers) with an oily/waxy agent.

I asked in one of your other posts, where is "NK"? Do they salt the roads there?

Hi Rooy,
NK is Northern Kentucky, right across the river from Cincinnati.
Yes, they definitely salt the roads when it snows.
Thanks for the info. I'll check with the guy tomorrow to see what type of stuff he's using. Now that I think about it, I think he said it was something called Rust Free.

What do they usually charge to do this type of work? Just curious. It sounds like a good idea to do it yearly if it's reasonable.

it may be a rust converter, like ospho, that turns rust and bare steel into an oxide that doesn't rust further. Its a good first step, but undercoating or oiling should be used in addition, otherwise when a rock chips the coating its gonna rust like crazy from there outward.
