Hi Iain, beautiful place Scotland but you really do get some bad weather that's for sure mate.

Yes Bob, north of Stirling do get some tough winters, but as long as you're prepared for it not really a big problem. Great area to live 👍

This fella recommends Fluid Film, which is available in the UK, he doesn't mess about either, if somethings no good he says it's no good.

 

 

A second, more in depth video from the same channel, both are worth a watch.

Thing is Japanese cars are not protected underneath for British weather and they do rust 😕

Mazda seem to be one of the worst in this respect.

Japanese cars are built in many plants around the world for many different markets, the protection they get depends upon their intended destination.

Cars built in Europe will get appropriate protection so nothing to worry about.

Dad had a Jazz and an Almera built in Japan but since both were for the UK market they were fine.

We had 2 Micras and a Note all built in Sunderland, all were fine. kept one Micra for almost 8 years and no corrosion at all, its now 16 years old and according to the MOT checker its still on the road with no serious corrosion.

But 3 people I know had MX5's from different markets. One was bought used on a trip to Hong Kong form a relative, total rust bucket. Another was bought new from Motorpoint but it was a car from the Cyprus market. No protection and rusted badly. The 3rd as bought as a new UK car, kept 8 years (only sold when the family increased in size) and was fine.

Last car I bothered Waxoyling was a 1980 Escort, it still rusted. Since then simply washed and driven with no issues.

Apart from the front crossmember that seemed to rot on all of them.

Last one I had professionally treated would have been about that vintage - a Datsun Cherry.

Got rear-ended into scrap long before it could have started rusting anyway 😒

Since then I've only used Waxoyl or the like on areas where work has been done and bare metal might be exposed.

The only car to die of rust was a Carina I had from new ... after 15 years and nearly 250,000 miles. (Top of the rear arches where the suspension attached.) It was a good car but I don't regret not treating it as by then it's handling, etc, was well behind the norm.

[Saxmaniac]

The best cars I've had for rust protection were Vauxhall from early 2000s. I don't know about more recently. Thick rubberised undressed, galvanised body and wax injection in body cavities. I ran a bore scope through interior of sills after 15 years and condition was as new.However suspension and subrfames very little protection.

Toyota was quite a surprise after this as the protection underneath is minimal. Normal lack of protection on subframe etc but other than some seam sealant, very little else underneath. Nothing in cavities so long term I'd have little confidence in factory rustproofing 

[Madasafish]

Dinitrol is easy to apply - (It must be warm for best results- giving a film which resists abrasion and is rust resistant.

Our 2003 D4D Yaris is rust free thanks to Dinitrol on inner sills and around rear floor/suspension etc. Treated c 2007 and then inspected every 2-3 years. (we have a garage pit which helps)

[Saxmaniac]

I've used Dinitrol and it's pretty good. The thin ML fluid seems to protect really well inside things like control arms plus, using it first as a penetrative fluid before applying harder waxes over the top. I've been experimenting with Fluid Film lately and that's looking excellent

Not in my experience. I've had 4 MX-5's 2 NA's and 2 NC's with one of the mk1's an import from Japan (Eunos) and the others UK cars and all eventually rusted extensively.

Just been thinking about the older Japanese cars near where I live.

Next door top side 08 plate Avensis, looks mint, never any trouble.

Next door bottom side 13 plate Mazda 6. Bodily looks great but has had costly DPF issues.

Across road P plate (not private) Mazda 626 (that's right, a 1996 car, its the 1992 to 2002 shape). Looks fine, used daily.

Bit down from that a W plate Corolla, I would be happy if any 20+ year old car of mine looked as good and its used several times a week.

There are more examples on the road but I don't suppose any of you lot with a grudge against Toyota's (and other Japanese cars) will believe me.

But this forum is no different to any I have been a regular on. On most non-Toyota forums disgruntled owners say they are buying another Toyota next. The worst forum I was a member of was the Nissan Note one. A few months after buying the Note I joined and said how happy we were with the car (which of course we were). The Forum Moderator came back and told me we were mad buying one and would soon regret it. A number of happy owners came on to support me but there was one very aggressive anti-Note member who when I answered his post I was banned, reason given, my posts saying how happy I was would possibly upset unhappy members. A number of the other happy owners were also banned soon after. Happy to say that forum looks a better place now that the moderator and other aggressive members have gone. People even say they are happy with their cars and get support form other happy owners.

Its sad when peoples only purpose in life is to try and make people look stupid for their choice of car. They should simply shut up and crawl under a rock.

Thing with modern cars is that they can look great on the outside but it's when you get underneath it can be a different story. It's not like the 1970s when most 3 year old cars would just be starting to get bubbles appear on the wings! If you're just going to keep a car a few years then change it rust isn't going to be a problem, it's those of us OCD types that want to keep it good for long term and no matter what the make, the underneath needs inspecting and protecting before rust gets out of hand. My friend just had replacement subframe on a 10 year old Mercedes for example 

[600rob]

I wash the underbody let it dry then apply either ACF-50-corrosion block or XCP rust blocker fluids.

it's a bit of a faff and a bit messy but only do it once a year and seems to do a decent job of protecting against new and keeping existing rust in check.

Did this annually on my 01 french built MK1 and never had any issues.

Recently got another MK1 tsport which is jap built. It's indecent shape underneath but definitely can see where there's a lack of sufficient undercoating compared to the French version so there's a few areas where rust is starting to form. Will use the same treatment method on this car and monitor to see how it goes.

I’ve used Dinitrol but it’s expensive.  The ones I’ve done still look like new after years.  

[Toymo10]

It's funny that this subject has come up, as I have a 3 month old Yaris and when we took delivery  from new, looking underneath I was surprised by no protection at all. Within three years there would undoubtedly be rust on most of the suspension surfaces. 

I have done what I do to every car I've had and waxoiled all the suspension. My other car, a  Volvo is eight years old was very well protected  from new and there is no rust at all after 8 years and 38k miles. BTW I clean and re wax every year. I see it as an insurance against  failure if you can stop any water ingress. and keep track arm threads and brake pipes from corroding.

Hi Iain,is the second hand car market in Scotland slower then elsewhere as I assume most motorists are aware of this salt problem. Has this also affected the prices.?

Can they not find something to melt ice that is not corrosive salty for example Scottish Whiskey

There's no such stuff. I wouldn't be surprised if you disappeared under a mountain of claymores and kilts. Hadrian's wall won't stop them.

WHISKY.

They'll set a pack of haggis on him, and string him up by the Bannockburns if he's not careful.

That spelling is however fine for the stuff from the emerald isle.

[Guest]

And to be further pedantic - is it Scotch Whisky?

[Cyker]

Not to be confused with Scotch Whiskers, for the discerning feline.
