Hej Frederik! So am I (looking forward to what's next and the end result!) - I have a plan, but also do what makes sense to do, and like the vacuum actuator, I don't always know what comes next. Red is the colour of my car, by definition, original and beautiful. The correct red, of course ![Smiley](http://www.matrasport.dk/forum/Smileys/default/smiley.gif) Years ago, I wanted her to be dark blue, and I still think that's a beautiful colour for the Murena, but that's not my car ![Wink](http://www.matrasport.dk/forum/Smileys/default/wink.gif) You are always very welcome here! This weekend will be busy with other stuff, but next weekend perhaps. We can figure out something on Messenger, I think ![Smiley](http://www.matrasport.dk/forum/Smileys/default/smiley.gif) /Anders

Judging from some of the photos of brackets and such, it is time to break out the concentrated Phosphoric acid, to neutralise the rust, before painting with Hammerite. That was some of the first I did to mine way back when. ![Grin](http://www.matrasport.dk/forum/Smileys/default/grin.gif) You're right, there are several items that need just that treatment! This one cannot be saved, though. But it's not the next thing to do: I've decided to steam clean the chassis and that will be my next job, and then brushing down the two rusty surfaces on the chassis, both in preparation for a layer or two of cold-galvanization. Expect more over the weekend ![Smiley](http://www.matrasport.dk/forum/Smileys/default/smiley.gif)

The front of the Murena is where lots of of wires, cables, pipes, attachments, bars meet. That's probably the most annoying thing about working on the front: It's a complicated "mess". Most cars have are the same in this respect, of course. Stripping the front completely is not on my agenda. My car is well kept and good, so there's no need to removing any suspension, brake system, wiring etc. But not stripping things does make things a bit more complicated: It feels a little like cooking a menu in a too small, unordered kitchen: It can be done, but it requires more concentration and moving things around - and probably a bit more time for thinking, planning, and coffee breaks ![Smiley](http://www.matrasport.dk/forum/Smileys/default/smiley.gif) I was going to upload a picture of the "mess", but then I had second thoughts and chose this one instead, taken in the evening sun yesterday. It's showing thin rust protection dripping out from the inside of the front cross member. To me, that's beauty ![Smiley](http://www.matrasport.dk/forum/Smileys/default/smiley.gif)

I'm probably going to leave most of it exposed as it is as it allows me to see if it "works". The zinga paint is supposed to re-galvanize the steel below by a chemical reaction similar to what happens in warm galvanization, just cold and therefore much slower. The only problem with zinga paint is that it requires a very clean surface, especially regarding the salty white corrosion which our cars naturally suffer from. Red rust is actually not as critical since the zinc can slowly "eat" through it, but the white salts create a boundary between the metal and the zinc-paint so that no re-galvanization takes place.
There are areas which I can't clean to the required standard, e.g. inside the beams. I will spray those areas with a very thin penetrating corrosion protection product based on linseed oil. This should stop any corrosion, including white rust. I plan to give the suspension components that tratement too, just followed by a layer of black corrosion protection which hardens to a thick layer (the linseed oil based product is extremely thin and seems to take weeks to harden, and even then it keeps flowing, so will need to be refreshed from time to time).
