I find the rear fenders of the W123 most prone to rust, and or course, the lower part of all 4 doors. Rust may also appear beneath those floor mats - which many of us may not be aware of.

The rust at fenders may be a little difficult to do on your own as part of the fender (depending on how rusted it is) may have to be "cut" away.

The rust beneath the doors however, may be saved by first scrapping or sandpapering of the rust, then with anti-rust applied, the lower door-portion can be easily sprayed to blend with the chasis color. This again depends on the severity of the rust.

There is this product in Singapore - or so I was informed by my brother, Kenny - that arrests rusts (electronically). This device emits electronic pulses every so often, from its fixed position in the bonnet and flows to the boot. Kenny reckons it works well as his cars had less rust-problems thereafter. The costs: approximately SGD600-00 including installation.

I am not aware of this product being made available in Malaysia, or the US.

Worth checking it out.
