CC Roof Rust

[Dano]

Hi,

Not sure if this is the correct forum... hope so...

I've noticed rust on my roof on the GSR around the rear window and a couple of tiny spots (where stones or something have chipped the paint) on my roof.

Can anyone recommend a workshop that i can goto to get this fixed? Id prefer to goto someone who has experience with this common problem rather than someone who doesn't...

thanks in advance.

Dan

Just buy a new skin there about $600 and get a panel beater to do a change over.

Might want to check the rails as thats there the rust begins. I change 4 of the 5 rails/ribs or whatever you want to call them

yep best method is to spend the rough grand on a skin and the ribs and have them changed over.

Yep, you need a new roof turret. Remove both front and rear windows, cut the old roof turret out and weld in a new one but this time use a non oxidising glue or spacer filler between the turret skin and the support bars across the top. Most CC models + CE and FTO's come out with a glue that actually oxidised and caused some kind of chemical reaction with the metal to bring on rust over time - plus the fact that they were never really painted and sealed all that well from factory under the turret. Mitsu didnt find out about it until several years later when rusty roofs were being reported. By that time they had several years of cars roll off the production line which used this glue unfortunately :roll: Using aircon often results in condensation buildup under the skin which accelerates the rust process

lucky my aircon doesnt work then 8)

I knew there a good reason why i took out my aircon 8)


i need to change my roof skin over as well :?

Its most common in dark models that are in Hot Climate that the aircon is being used frequently, the ceiling skin has a type of carpet under lay attached to the ceiling skin as a sound deadener this absorbs moisture trapping it in-between the turret metal skin and the ceiling as its hot and humid its the perfect environment to break down the panel sealant used all this = The Dreaded Mitsu Roof Rust :x

One of the first signs normally befor bubbles appear is small black granuals inside the roof ceiling light lense as the sealant breaks down and is shaken around and normally builds up there first.

I think that should also be added to the Evo GSR buyers guide.

You can also see the roof rib that the light it screwed to so a quick unscrewing of the light fitting on the roof will let you see the turret ribs first hand.

BTW you can now Join the Mitsu Turret Rust Replacement Club not the kind of club you want to be in but there are a lot of us that have joined :x

I urge everyone who hasnt yet done so to remove their headlinings in their cars and take out that shitty sound deadener that absorbs moisture and aides roof rust. If you dont know what I mean, this frikken brown shit below stuck onto the lining \/ \/ \/ \/

Car above was a 1998 model M21/CC coupe after only 7 years into its life (Had the roof turret replaced in 2005 - was a Northern Territory then QLD car so aircon would have been used a fair bit). New turret was $600+GST, and cost us $1200 to install and paint and the result is below

 

[OFFON-4]

Im still looking for the front rib cant find one

 

[evopwr]

honestly, i DONT WANT TO KNOW what my roof looks like under the lining :shock:

:lol:

load bearing rust... i think i have sone of that too...

 

[evopwr]

i've just removed my headlining to be delightfully surprised none of that inner roof rust! must be a coupe/m21 thing...

 

[rock_it]

I must admit I am scared to know what mine looks like... Maybe I will take a peak ...

 

[Nick_CD9A]

my car is in the process of getting it repaired, sisters boyfriend said the "sealer" is the cause for it . i always asumed it was the lining

 

[trevmcrev]

Prolly a good thing my cars had no roof lining in it for the last 7 years :lol:

 

[ShaunEVO]

if your repairing your roof...probably perfect timing for that aftermarket sunroof you have always dreamt about :wink:

 

[fish]

hmmm sunroof...


i know what i'm doing tomorrow, checking underneath!
