Hi Guys, I am new to the Briskoda forums and have a problem with my Fabia 2. The recent MoT 0n the aforesaid car had an advise on surface corrosion on the brake parts and also steering and suspension components.  Although not a Failure I was advised to "keep my eye on it"   The garage said that this was part of the new MoT test so I was obliged to do something about it!  Is it possible to rectify this situation which I am unable to do myself or is there some sort of a treatment to remove this corrosion. Situated beneath the vehicle which is going to get all of the salt etc. in the Winter and in spite of going through the car wash (including the underside) I do not know what to do to rectify the situation.

Many thanks,

Jeff

Sounds like normal to me. Without seeing it it's very hard to judge though.

All cars rust on those parts.

 

Keeping rust at bay on the underneath of a car is a labour of love.  It's all hard work and in the end, at best, only slows down the process. In the past I have wire brushed the underneath of cars, applied Kurust, then black Hammerite and then Waxoyl over the top. Be prepared to get very dirty, bang your head and skin your knuckles.....oh, and spend a few quid as well.  This may stave off the inevitable by a few years......

 

Nowadays I don't tend to bother with our cars too much, I just buy a new(er) one periodically.......

 

But my motorhome I need and expect it to last a lot longer than the cars, it's very expensive updating it. So I lie on my back underneath it every year and spray a rust treatment. I used to use Waxoyl but it is such a filthy job I use ACF50 on this one, from new. It is a bit cleaner and easier to apply, but more expensive, I spend about £50 a year on ACF50.

 

Only you can decide whether you can be bothered and are prepared to spend the money....!

As Wino says surface rust on suspension/brake parts is normal (they are not galvanised as the main body is) .

 

However it is worth keeping an eye on some components as eventually they could fail with rust eg rear axle/spring cups, front subframe. I'm a fan of getting underneath every year or two to check and cleaning off and possibly preserving in some way , myself I've found Owatrol oil to be amazing stuff - looks like clean engine oil when it paints on but it soaks in and seems to eventually sets like a kind of clear resin and doesn't wash off!

 

As an example my wife got a garden ornament a couple of years ago that when put outside became covered in a light surface rust the very next day - I gave it a bit of my Owatrol oil treatment and two years later it's still looking perfect. 

 

I also am a fan of ACF50 (as mentioned above) but it's more prone to washing off but it's fabulous sprayed in door bottoms etc as if soaks into seams. 

 

Never paint with underseal - it seems to make things worse!

As a classic a car owner I can vouch for that!

In the past when restoring cars I used to paint/drown the whole underside in clean engine oil and then paint waxoyl underseal over the top(yes it eventually sticks!) - this did work well and afterwards the protection seemed to remain tacky. This process is really really messy though and it needs to be done on top of good condition bodywork (ie after any welding - not trying to "fix" old bodywork)

 

However if you paint the underseal over the top of existing dry rust it doesn't go well long term and you can't see it until major damage has been done. I like the owatrol oil as you don't need that much prep work although I make sure mud/silt/loose stuff has been removed. It's very effective on axles/springcups/suspension parts/subframes and or in the case of my wifes Fiat Panda  the sump!

 

I just do a holding protection now as my days of car restoration are over - think I have some arthritis because of endless hours angle grinder use! I used to have two (or even three!!) on the go with cutting/gringing discs and a wire brush

Blinking annoying when people mention anti rust products that you don’t currently have - but I will have soon! 
 

Ebay to the rescue!

Hi Guys Old Thread I know but I been told my rear subframe and components on my skoda octavia 2007  is showing signs of corrosion and the mot guy said put  waxsol but reading up on it it does sound really messy does Owatrol Oil work just as well, it is covered in dirt I was thinking of using my jet spray to try to clean off any loose dirt, I really like the car and cant afford to replace it

Finnagans or Hammerite Waxoyl  works well, and clear rather than black for me.

Clean / wire brush the parts, use rust inhibitor, let that do its job / react, then use clear Waxoyl.

I doubt you will get a wire brush into all of the parts will do as much as i can with a brush though is Owatrol oil the rust inhibitor is it?

You can only do what you can do.

 

Never seen or heard of it before.  I was a car sprayer.

I used to restore cars and until a couple of years ago I'd never heard of Owatrol oil. I've found waxoyl etc was fine to a point but always seems to eventually wash off suspension/ axle parts (if I was restoring this is not what I would have used anyway). A Landrover nut friend introduced me to this stuff (it's fab on rear axles etc) and it's been fabulous - Obviously you need to get rid of dust/dirt but then it's easy to apply (spray or brush) and it seems to survive the elements being thrown at it really well. As with anything always worth keeping an eye on. 

 

As an example I applied to the sump of my my wife's Panda that was rusting badly - two years on it still seems good. It set's clearish so you can see if there are still problems - in a way that you couldn't with underseal etc until it was too late. For stuff like suspension parts exposed to the elements this stuff is great - don't use underseal! 

 

It's not cheap but worth trying a smaller size to give it a go and see what you think.

 

PS I also used on an outside garden "thing" that my wife got as a present which started rusting from day one and looked awful very quickly. A wipe over with this stuff and many years later still looking OK. This was just a wipe over with the stuff using kitchen roll - If you look at the top one this gives you an idea of how it sets, it paints on looking like oil an kind of sets to a kind of satin varnish finish  - and stays that way.  I also now use with outside lights on my house that seem to be susceptible to rust.

My tin of Owatrol oil is still  intact, warmer weather + changing to summer wheels/tyres + servicing brakes will see me using some!

Great minds think alike - I always have a pot to hand when swapping summer/winter wheels. I always check subframes, suspension components/bolts and things like brake backplates and have a paint around as needed. A quick few minutes doing this every year could rather increase the life of the car and it's components.

I feel a purchase coming on. Thanks for the Owatrol recommendations gents.

this Owatrol oil sounds really good is it worth using Waxoyl  on top of it?? or maybe a Rust Transformer before use? 

I am going to get some as well, it seems to be a lot cheaper here and available over the counter, too cheap perhaps, is this the same stuff?

Make sure surface is clean/dry and then just brush or spray it on.

 

I find waxoyl washes off - Owatrol doesn't

Next time I'm in France (might not be anytime soon!!!)  I'll stock up then. 

 

I might be using quite a lot soon on the fleet as I've nearly completed the Covid lockdown home decorating jobs!

what about Rust Transformer before use John do you think its needed cost?

I've never bothered - I suppose it wouldn't do any harm
