Waxoil. Excellent protection or Automotive Pebbledash?

[Colin]

On a recent inspection of the underside of my 325is i found a small area of rust below the battery compartment in the boot. I have cleaned it up and applied some rust stopper. I have been looking at Waxoil as a method of preventing any further outbrakes but I am concerned that this could just cover up any more rust and allow it to develop under the Waxoil undetected. I also do not know how easy it would be to carry out any further repairs when everything is coated in the stuff. Does anyone have any experence of the pros and cons of this stuff?

I'm going to use this in the sills etc http://www.bilthamber.com/dynaxs50.html the classic car fellas reckon it is very good and outperforms Waxoyl.

[Colin]

Sound good and not a bad price. Cheers for the info

Waxoyl has always worked fine for me. Just make sure you're not charged over the odds for the treatment.

[Lordschleife]

Waxoyl do an underbody seal version (black container instead of yellow) you can get it in a spray can from halfords. That will be better than std waxoyl for an exposed area

This is the stuff I used, although bought fro ma motor factor rather than the highstreet

[Martinaston]

Does anyone know what the original underbody seal is called ?
The white rubberised stuff.

Nice thread , as im after something to use on my sills to replace the stone chip look. Halfords have the waxyol stonechip stuff, but its really thin, i wanna re do the sills and paint them before i sell the car to clean it all up

On the sills use tyre paint as it stays quite rubbery stopping it getting chipped.I did this on my first e30 and it was spot on.

waxoyl is good stuff and does what it claims. i've applied it liberally to the underside of all my cars over the years, once a year around easter time once the frosts have stopped and there's been some rain to wash to the salt from the roads. it halts/slows almost to a stop any corrosion that's already there and certainly prevents more corrosion from forming.

waxoyl themselves claim that a coating should last 2 years.

if you paint/apply it over road salt or wet muck and then expect it to work then that's the actions and thoughts of a loon. it's pretty horrible cleaning the underside of a car then waxoyling it but the feeling once done and almost certain knowledge that there'll be no welding bills come ticket time is worth it i reckon.

Back in the 70`s , a masive selling point for any second hand motor was that it had been "waxoiled" and "Ziebarted" (spot on underseal) from new.
Hear`s a question, were all E-30`s properly undersealed from the factory or was it extra? Mines an 86 and the underside is Brill, Am I alone?

HOW MUCH!!

You can buy 5 litres of Waxoil for about £15
Worthwhile investment IMO

Heres a good deal

I thought the "in thing" in the 70's was to get your sills filled with old engine oil

HAD A GUY OUT A COUPLE OF WEEKS AGO TO REMOVE A COBRA ALARM WHICH WAS PLAYING UP,HE USED TO WORK FOR SYTNER IN NOTTS DURING LATE 70S EARLY 80sHE GAVE ME A GOOD TIP WHICH WAS TO TAKE OUT BACK SEATS AND CARDS AND WAX OIL THE REAR ARCHS FROM THE INSIDE. I INTEND TO ADD THIS TO MY TO DO LIST THIS SUMMER. HOPE THIS IS USEFULL GUYS

[SwirlyE30]

The thing in the 70s was to make a car out of a lump of steel, then wonder why everything started to rust !!

[Martinaston]

Vauxhall used to leave them out in the rain unpainted so when it came to spraying them it would stick better

[Lordschleife]

Any one ever see the Clarksons car years about who killed the british car industry, shocking

[SwirlyE30]

No mate, what was it about?

[TVRTASMIN]

The undersealing done in the 70's, particularly on British cars including Landrovers, was a form of bitumen and trapped rust and moisture.

After a few years the outward appearance looks OK but take a scraper to it and you could often dig straight into the box section which had turned into crumbling rusty flakes. The rest just scrapes of in rusty sheets with a bitumen coating.

[Lordschleife]

- double post -

[Lordschleife]

Erm what the title says!

Lots of stuff about British cars in the 70's, strikes, cars leaving the factory with filler already in, piss poor design - one was designed too wide to fit through the tunnel between two parts of the factory, so the bare unpainted shells were driven 1/4 mile in the rain before spraying etc etc

Keep an eye out they're always being repeated on UK People, worth watching the other ones too - the New Romantics (80's hot hatches) is particularly good

If you have got rust "YOU HAVE GOT RUST".

No matter how well you clean it up it is still there. You need to treat the area with a good rust converter which makes the area inert. No amount of waxoyl or similar will stop further rusting, it will only slow it down.

After using the rust converter you can spray the trouble spot and surrounding sound area with a zinc type primer before applying a finishing coat.

Have a look at this site http://www.rust.co.uk/ , in particular fe 23 and the epoxy mastic.

I used products from this company in the past and they are excellent, but like everything else the secret is in FOLLOWING the instructions, paying particular attention to the guidelines for preparation.

If it keeps oil rigs in the North Sea afloat it will keep an e30 on the road for a few more years!

Some of you guys have missed the point.
When you bought a new car , you had it Waxoiled and Ziebarted from new, by people who only did this for their job.

My question also was did all E-30`s from new , have the same treatment?
Cheers, Mart

ps I used to and still do , buy very second hand cars.

[martauto]

Just seen your post "Dan The",
You are quite correct , but ,today we could not do this.
Would you want to ?, do we have to ?

Mart.

[DanThe]

Would I want to fill my sills with old engine oil? Not a chance!
If I did I reckon Environmental Health would have a thing or two to say about it

[martauto]

Cheers mate, keep lucky.

Most M20s make a fairly good job of coating the underside with engine oil without any external help.

Another of Brians classic quips!

[Simon13]

E30's were fully undersealed from factory i'm sure

[bigkev]

you are right there brian (un)fortunately mine has a fantastic selfpreservation undercoating system you just add oil in the usual manner
(via the rocker cover)and the engine provides the under body with a perfect thin film of old engine oil over everything from the front of the sills rearwards(a bit like a scottoiler on a motorbike chain)
i am thinking of selling an UNDERBODY SEALING KIT consisting of some knackered old cam and crank oil seals, just add oil













dont laugh too soon mine's 22 yrs old with not a spot of rust underneath
