waxoil! are you sure?

[snickers]

What is it with people and waxoil!

My new van for work came with an absoloutely pristine underside with not a drop of anything on it except bright shiny metal!

If waxoil is so important why dont VW and the like stick it on the bottom of their vehicles??

This is only a question because I dont know the answer so please dont take offence!!!!

Without any form of sealant how long will the shiney metal stay shiney? I think it is a cost cutting thing with the manufacturers

With all respect if it has a 12 year anti corrosion warranty on the whole vehicle I can't imagine it rusting before then!

Im certainly not keeping my 96 Bongo for 12 years and wonder how many other people will!!

Just a thought................

[David Edwards]

The 12 year anti corrosion warranty is full of catches, e.g. if you see any rust you must get it done straight away and it only covers certain parts of the vehicle, I would read the small print there are loads of traps in it. Every vehicle I have had I have had undersealed simply so I know it has been done properly. Some of my friends and work vehilces have fallen foul of the tin worm even with a guarantee. I would simply advise anyone, get it done. Happy motoring.

The whole point is, chaps, that the Japanese do not use salt on their roads and neither do the tend to keep their cars as long as we do.
The underside of your nice new British (is there such a thing?) car may look all shiny and painted, but now days they underseal it and then paint ON TOP of the underseal.
The reason manufacturers don'y use Waxoyl is because it is inferior to underseal and washes off over a period of time.
The Bongo underbelly paint is VERY thin. Mine had only done 22k miles when I had it it and the original tyres were perished, not worn out, so it obviously had not been used much and when I finally plucked up courage to look underneath there were tiny little pin prick rust marks starting.
So beware!

Sooo, what should I do about mine - it too has very slight rusting, more of a discolouration in places really. It is actually very clean. Can I get it undersealed on top of that or do I need to treat it with something else first?

You could give it a coat of rust remedy, a milky liquid that turns rust into a safe solid.

But I am led to believe that Waxoil stops rust oxidising, so it does a similar job.

All t best,

Had mine treated by Rustbusters of Poole. I originaly thought that it was a bit pricey at £575 ! When I picked it up Phil, the owner gave me a conducted tour of the underneath. I have used, abused, and owned several vans, but have never seen one with so many cavities as the Bongo. Yes superbly built, like all Mazda's, but any metal will succumb to the dreaded rust eventually. Yes Waxoyl will wash off, but not if applied to the box sections and all double skinned panels. The black stuff (underseal) contains Waxoyl, but is mostly bitumen, and when dry can be steam cleaned!!! Being part way through a camper conversion that costs £1500 in materials alone, plus the buying price of the vehicle, it would be silly not to protect that kind of investment. I highly recommend Rustbusters !!!![/i]

aahh I see!!

If manufacturers waxoiled the vehicles from new, think how long it would be before they started rusting and owners decided it was time for a replacement. They wouldn't sell quite so many new vehicles. A bit like stainless steel exhausts, fit a mild steel one and replace it every couple of years or fit a stainless one and forget it.

Waxoil: use clear waxoil where it is likely to be seen, such as under bonnet, door internals etc. Any drips through drain holes will be almost invisible.
Use black waxoil under the vehicle.
Waxoil remains flexible, so wont crack allowing water ingress, and also kills any minor pre-existing rust and prevents any new rusting occuring.
Underseal will crack allowing water ingress which gets trapped behind the underseal, you the get more moisture forming due to condensation(viscious cicle) and consequently rust.
For what its worth, stick to the waxoil

'Cos it's galvanised steel, won't rust (so easily )

[snickers]

aaah I see !

[egor110]

How easy is it to do this yourself? Is it just a case of get underneath and paint everything you see?

[Dave up north]

Have a search round your local garages/bodyshops and ask how much.
Its a messy job and better if applied with a spray gun. Also easier if vehicle is up on a lift.
My dealer did it for me as part of the deal, but I would suggest if you ask a garage to do it, this would be easier.

This is positively my last comment on waxoyl !! The underseal they use, the black stuff, is called Hardwax Underbody Protection. During the conversion of my vehicle I needed to feed various electrical wires through some of the body cavities. "Bertie" squirmed a bit but seemed to enjoy it in the end ! But in the process I found that the clear wayoyl applied under pressure by Rustbusters, had in some places reached almost a metre above "Berties" bottom ! The black stuff on the underneath has been on for a couple of months now, and is hard and solid. I have'nt used a steam cleaner yet, but have used a high pressure washer with absolutely no effect on the finish. Keep up the good work, a great site.
