R33 Gtr - Is This Rust Common? (hard To Explain - Pics Attached!)


Recommended Posts

Hey guys and girls,

I have a bit of rust in a section which is a bit hard to explain. its near the bottom front window plastic and under the side guard. (i've taken a few pics)

It hasnt gotten any worse in the close to 3 years i have owned her and only looks like surface rust. I've been meaning to sand it back, seal and recoat with some touch up paint for a while but havent got around to it yet.

Anyway, is this a common problem? Does anyone else have it? :(

Any info or advice would be appreciated.

Cheers!

Just a couple of Qs...

It looks as if there's been some fixed-up panel damage > re-weld does it not?

It looks like surface rust only; but is there any bubbling especially if you press on it?

Have the corners of the panel bolts been chamfered as if the panel's been taken off?

Does water sit there after rain or wash?

Does the moulding at the base of the windscreen need replacing?

btw, surface rust can lead to 'cancer'

if its stabilised for past 3 years why worry about it - for peace of mind a quick fix is to get a spray can of fish oil and spray the discoloured area this seals and prevents against any rust - will kill any rust if it is rust - done !

Touche'... that is what I am going to do until one day I can get a respray!

I think you will find its not corrosion in the usual sense - I think its that the finish colour has been applied very thinly over the etch prime in out of place areas when the body is painted at the factory - you see the same discolouration in various places in some Jap (and other country) cars e.g. inside where intrusion bars are fitted in doors , in hard to get to places on the body panels where front bar is fitted etc - its normal , just like orange peel finish was normal on outer underside edges of US made cars some years ago

where can one purchase this fish oil stuff from? do they come in them sprayable cans?

repco supacheap ..........everywhere - about $6-8 usual larger size spray can

when it dries fully it is usually clear - you could spray paint over it if necessary

yeah my series 2 gtst has the eaxact same surface rust..... just how the buggers are.... i'd only really worry about rust if you see it bubbleing and going down deep..... usually first place serious rust starts on our imports is under the wheel arches where the japs throw salt on the icy roads to reduce the slipperyness of the roads.....

hey ya'll just been doing some reading on the various treatments of rust ... apparently fishoil is good for preventing any new rust but it won't get rid of any existing stuff plus it doesn't penetrate existing rust which could lead to more rust

Apparently a product called 'Penetrol' available from Bunnings actually penetrates rust deep and takes away the Oxygen and stops any further rust from forming .. apparently don't even need to clean the rust spots up before applying this stuff. Anyone used it before ?

  • 3 years later...

I've got alittle bit of this surface rust starting both sides, Do not like looking at it. Cars mint other then this, So would like to fix it.

How would I go about fixing it. It looks simple enough to do myself, Taking side skirts,front fenders and front bar off is the only fear I have, Then sand it body filler if needed then paint it, And make it look beautifull again, Has anyone had this and fixed it. Did you go to panel beater or DIY it?

Or is going this far not necessary, it just looks sh#t

The Conversion Paint is easily brushed on with a quality long hair brush. It does not affect the colour of your existing paint, because it dries clear. Within an hour the difference is there before your eyes.

The Fish Oil I have is in an aerosol can.

This process stopped any more rusting of an Alfa Romeo in its tracks. Any automotive paint shop has it - but I don't know about Repco/Auto1/Supercheap

Hmmm, I usually treat rusts with the usual wire brushing for removal, then zinc spray (lightly), then spray paint over. No oils of any kind or rust converters. Opinions in this gents? Never knew about fish oil until reading through SAU forums, got to learn boatloads, especially from the build section.

I had the same problem and although it wasnt progressing over a few years i still decided to fix it. Just remove the arch, wire brush and sand it back as far as u can to really clean it up. Its usually just surface rust with some pitting. Then apply some rust converter (which youll get from supercheap etc.), give that the recommended time to penetrate and then u should be able to blend the colour or ive just sprayed the area matt black because it cant be seen unless u look. Thatll hold it off for quite awhile. Ive had no issues since.

    • From there, it is really just test and assemble. Plug the adapter cables from the unit into the back of the screen, then the other side to the car harness. Don't forget all the other plugs too! Run the cables behind the unit and screw it back into place (4 screws) and you should now have 3 cables to run from the top screen to the android unit. I ran them along the DS of the other AV units in the gap between their backets and the console, and used some corrugated tubing on the sharp edges of the bracket so the wires were safe. Plug the centre console and lower screen in temporarily and turn the car to ACC, the AV should fire up as normal. Hold the back button for 3 sec and Android should appear on the top screen. You need to set the input to Aux for audio (more on that later). I put the unit under the AC duct in the centre console, with the wifi antenna on top of the AC duct near the shifter, the bluetooth antenna on the AC duct under the centre console The GPS unit on top of the DS to AC duct; they all seem to work OK there are are out of the way. Neat cable routing is a pain. For the drive recorder I mounted it near the rear view mirror and run the cable in the headlining, across the a pillar and then down the inside of the a pillar seal to the DS lower dash. From there it goes across and to one USB input for the unit. The second USB input is attached to the ECUtec OBD dongle and the 3rd goes to the USB bulkhead connected I added in the centre console. This is how the centre console looks "tidied" up Note I didn't install the provided speaker, didn't use the 2.5mm IPod in line or the piggyback loom for the Ipod or change any DIP switches; they seem to only be required if you need to use the Ipod input rather than the AUX input. That's it, install done, I'll follow up with a separate post on how the unit works, but in summary it retains all factory functions and inputs (so I still use my phone to the car for calls), reverse still works like factory etc.
    • Place the new daughterboard in the case and mount it using the 3 small black rivets provided, and reconnect the 3 factory ribbon cables to the new board Then, use the 3 piggyback cables from the daughterboard into the factory board on top (there are stand offs in the case to keep them apart. and remember to reconnect the antenna and rear cover fan wires. 1 screw to hold the motherboard in place. Before closing the case, make a hole in the sticker covering a hole in the case and run the cable for the android unit into the plug there. The video forgot this step, so did I, so will you probably. Then redo the 4 screws on back, 2 each top and bottom, 3 each side and put the 2 brackets back on.....all ready to go and not that tricky really.      
    • Onto the android unit. You need to remove the top screen because there is a daughterboard to put inside the case. Each side vent pops out from clips; start at the bottom and carefully remove upwards (use a trim remover tool to avoid breaking anything). Then the lower screen and controls come out, 4 screws, a couple of clips (including 3 flimsy ones at the top) and 3 plugs on the rear. Then the upper screen, 4 screws and a bunch of plugs and she is out. From there, remove the mounting brackets (2 screws each), 4 screws on the rear, 2 screws top and bottom and 3 screws holding in the small plates on each side. When you remove the back cover (tight fit), watch out for the power cable for the fan, I removed it so I could put the back aside. The mainboard is held in by 1 screw in the middle, 1 aerial at the top and 3 ribbon cables. If you've ever done any laptop stuff the ribbon cables are OK to work with, just pop up the retainer and they slide out. If you are not familiar just grab a 12 year old from an iphone factory, they will know how it works The case should now look like this:
    • Switching the console was tricky. First there were 6 screws to remove, and also the little adapter loom and its screws had to come out. Also don't forget to remove the 2 screws holding the central locking receiver. Then there are 4 clips on either side....these were very tight in this case and needed careful persuading with a long flat screw driver....some force required but not enough to break them...this was probably the fiddliest part of the whole job. In my case I needed both the wiring loom and the central locking receiver module to swap across to the new one. That was it for the console, so "assembly is the reverse of disassembly"
    • But first....while I was there, I also swapped across the centre console box for the other style where the AV inputs don't intrude into the (very limited !) space.  Part# was 96926-4GA0A, 284H3-4GA0B, 284H3-4GA0A. (I've already swapped the top 12v socket for a USB bulkhead in this pic, it fit the hole without modification:) Comparison of the 2: Basically to do the console you need to remove the DS and PS side console trim (they slide up and back, held in by clips only) Then remove the back half of the console top trim with the cupholders, pops up, all clips again but be careful at the front as it is pretty flimsy. Then slide the shifter boot down, remove the spring clip, loose it forever somewhere in the car the pull the shift knob off. Remove the tiny plastic piece on DS near "P" and use something thin and long (most screwdrivers won't fit) to push down the interlock and put the shifter down in D for space. There is one screw at the front, then the shifter surround and ashtray lift up. There are 3 or 4 plugs underneath and it is off. Next is the rear cover of the centre console; you need to open the console lid, pop off the trim covering the lid hinge and undo the 2rd screw from the driver's side (the rest all need to come out later so you can do them all now and remove the lid) Then the rear cover unclips (6 clips), start at the top with a trim tool pulling backwards. Once it is off there are 2 screws facing rearwards to remove (need a short phillips for these) and you are done with the rear of the console. There are 4 plugs at the A/V box to unclip Then there are 2 screws at the front of the console, and 2 clips (pull up and back) and the console will come out.
