Mercedes 300SE Lang

The Front drivers side has a bit more rust repair required esecailly under the brake booster. The booster had to removed because of a lack of brakes.IMG_0093

This is the section under the brake booster ,the round hole is where the booster is mounted to the car . this sort of corosion is caused by leaking brake fluid removing the paint .


This the front inner part under the positon where the air cleaner is mounted . Rust has eaten the inside of the upper chassis section out .


And… the underside of the booster . No wonder the car was idling fast and without brakes.

the new doors are in process of being derusted .:-)

Nest step will etch priming then priming in preparation for paint.

measn while in the Front the rusted parts have been sought out ,the left side is qite good (apart from the sill sections)


On the Right side the booster will have to removed to get at the rust under it, leaking brake fluid has stripped off the paint and resulting moisture has attacked the steel.


the bottom of the front chassis support will need to be replaced.


In the left front guard it can be seen that the PVC undercoating covered everything,unlike lesser Finnys.



The fuel tank sender shows that it is basically shot.

All the way from W.A is this horizon blue 300SE with some serious rust problems. Not so unusual in a finny but serious enough to require a lot of work to rectify.

IMG_0069 (1) Right front chassis strengthening member rusted out . Rain water gets inside this section and if the lower drain holes are blocked,they eventually rust away . This particularly bad as that is the air cleaner visible in the center.
