Default about rust on our volvos

Hello you all,

So i wanted to tackle this subject, because sometimes I have the impression of loosing my time wanting to save my volvo. I struggle to keep it alive, and I really want to ride it until the motor is done ( 120k, so i count on taking the 240 on the road until there is no more gasoil to pump at the station) . When I bought the car , it was rust free (on first look for sure). It s been one entire year for her, enjoying the fresh air of the sea. Well I'm enjoying, and she's not.

I saw a very bad rust spot behind the rear wheel, and multiples little spots all along the car.

Now, My brother is a fine welder ( lte's say he is ok) and we both have some experience in composite work .

stop me if I misunderstand, but rust has to be completly eliminated before thinking about being realeased of the thought of this cancer coming back? If it s the case, I it would be a tremendous work, isn it?

How do you deal with that problem ?

240 body is known for rust being a common issue in salty areas. However there are things you can do to reduce the tendency. Beyond that, only option is to live with it.

If there are any chips or breaks in the paint, seal them up immediately to keep rust from being able to take hold.

Oil coating on underside is sometimes helpful (many folks in the US Midwest swear by this).

Any rust repairs, make sure they are sealed up well with good paint or you'll see it come back.

It's a never-ending battle! Part of the "fun" of owning an old car. But if you can keep it stabilized, it can be managed.

I've had my vehicles hot oil undercoated for several years now and it has either stopped or retarded most of the rust formation on the undercarriage & body. (I'm in Upstate, NY...plenty of snow and salt.)

Something like Fluid Film or applying grease to potential problem areas should also work similarly.

The only way to successfully eliminate rot, to my knowledge is to remove and replace the problem section of metal. Surface rust should be a bit more forgiving if adequately sanded and sealed.

Yeeah! That's the spirit I need to be inspired of!!

Yes. About sanding surface rust, what do you guys use?
