It seems that there is kind of design flaw at least mk2 Jazz/Fit. And maybe thet mk3 suffers from same flaw. The begining of the rear wheel archs, just front of the rear wheel, has some odd slot where all stones, sand, tar...etc can gather up and start to rust the whole arch.

Has anybody done any development how to block that spot?

And why the heck there is no wheel well lining at the back? Is there any aftermarket linings out there?

Few photos will help to know what I mean.

This is from mk2. The arrow points directly to the flaw.


This is from mk3, it's not the same, but similar. And potential risk also.


This is also from mk3.

 

They are not Mks. They are GD, GE or GK.

My GE has been through 7 Cdn winters and no rust. Just keep it washed.

 

I thinks that it depends where you live. Even in Europe, where I live, we have MK's, mainly in UK, I beleive. But it is just the same for me

We use so much salt during winter and due the freezing temperature, it's not possible to was car during winter. Ideal is to have whole wheel arch covered with that rubberized mass (tectyl eg) and then have plastic wheel liners, like in front. It would also reduce sound which would be very welcome...

 

Well I learnt something today. I had never heard them referred to as Marks.

We have freezing temps too so I wait for a day a bit above freezing to go through car wash. So maybe every 3-4 weeks.

If you are concerned maybe just spray it with undercoating. I would be concerned by covering this area it would create an area where salt could get in behind what you add and speed up any rusting.

 

Nice to educate Try this: https://www.google.com/search?q=jazz+mk2

Maybe I just spray some undercoat and brush some more after first sprayed layers dry out.

I have to figure out some protection for the wheel arch edge, the very edge. As we also use small stones and sand to add friction to the streets, it's extremely pain for the bare metal. I already bought clear plastidip-kind of product (different manufacturer). I'll try to add it only at the edge. It's going to be hard to apply it nicely only at the edge. Anyone done that?

 

If you do spray or paint try putting masking tape down first to get a sharp edge

 

MKs refer to "generations".

The GE8 is the MK2 Fit/Jazz

As far as that spot is concerned, just wash the cas every now and then making sure to remove sand/dirt that gets trapped there.

 

Not possible

 

No car washes at North Pole?

 

Of course there is, but it's extremely difficult to work with water when it's eg. -20 celcuis

 

I noticed this same rust liability some months ago and agree that it could be a problem in some regions. I live in the southeastern U.S. where temperatures are milder and road salt is rarely used, but I always sweep the sand and pebbles out and give it a good rinse.

 

I would not worry about rust at -20C. Too cold to rust. We get that cold here as well but surely you must get some warmer days where it is possible to go through a car wash. Anyways I am not worried about that spot. I am almost 8 yrs old and no sign of rust.

alco, I always give that area a good shot from hose when washing the car in summer.

 

I've read many articles about the rubberized / tar undercoating versus oil rustproofing and almost all of them were warning against the rubberized type undercoat because if it's not properly applied when the car is 100% clean and dry then it will actually increase the chances of it collecting moisture, dirt and rusting a whole lot faster.
Also even when properly applied on a clean surface, the rubberized material can crack over time thus allowing salt, dirt & moisture and keep it there again rusting the metal prematurely.
Oil spraying once a year (spring, summer, or fall) tends to be your best bet.

 

I'll have to chat with my friend, how did rusptoofing to the car in his previous job. Something like that:

 

My 2009 Fit finished it's 11th winter in the cold north and also suffers from this problem.

Honda could have installed plastic wheel liners, but didn't. Instead, they sprayed undercoating material in this area, which seems to work well enough.

This area takes an incredible beating from road debris, sand, and rocks. Rust just started in this area on my car after all these years. A small area of factory undercoating was abraded where rocks build up and rust started forming on the metal. Some paint around the fender lip was chipped away, causing rust start to form there too.

My fix was to wash everything really well, and then spray it with black Rustoleum spray paint that I already had. It looks brand new in that area again and only took around five minutes and around $1 of paint. Even if I have to touch things up every year, the car should keep looking good for a long time.

 

Same here on my 09 Sport. Not really a lot as I had it undercoated when I bought it. So I did like you and used Rust-O-Ieum I believe it was last summer. Last Fall I had it undercoated again. The first hand wash this year and it is looking line new still.
