Mercedes W112 Rust repair ,More progress.

Rear panel repairs.

The rear panel looked straight to begin with but there was tell tail signs of body filler which was falling out. After stripping it back to the bare steel ,it could be seen tht the panel wasn’t too badly damaged ,

 

The white stuff is old body filler which will be removed.

i rebuilt this engine 3 years ago but it was plagued with a leaky rear seal . It’s a 10 hour job to get it out of the car and the car isn’t driven much so it took a while to fit it into the schedule .

 

300SE W112 rust repair .

After Christmas 2016 and I’m slowly catching up with all of the work in the shop,first up is further rust repair on the W112  300SE lang. under the booster it had rusted, not badly ,just ugly …

IMG_0085.JPGYears of spilled brake fluid has burnt off the paint ,leaving the steel bare and open to rust.

The rusted parts have been removed and inside the crossmember cleaned and rust treat .

New top piece has been cut out of Zinanneal 1mm  to match the existing panel,

because of the complex shapes ,the replacements have to made in cardboard first to get all the shapes organised first.

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 .

IMG_0095

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.

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.

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.
