Flooding sills and chassis to stop rust.

[dhracer]

With all due respect Petrol, while I find your studies fascinating I can't see the relevance. You can try and accelerate corrosion all you want but it won't make a difference unless you're leaving it for a long time. The corrosion tests here at Millbrook are pretty hardcore, more than just throwing road grit at a plate dude.

While that is true even from those first pics I can see that waxoyl doesn't look to perform as well as that other stuff, so it could help us to discount some products quite easily

[j4mes]

how about using the "carpet" bmw is now using in their arches?? would this help to protect our inner arches

[Petrol]

Just looked at the website, facilities there are "Accelerated corrosion simulating 1 year in 2 weeks " Do they publish any results?

I guess the answer to this is no

[Shaziman]

i was given this link to an MR2 site. The MR2 guys seem to think that this method is the shit, see what you all think:

For those of you who can't be bothered to register:

"take one tin of tetroseal underbody sealant
pour into large bucket
add 25% old engine oil
add 25% gear oil
mk2 owners pubes are optional at this point

take a wire coathanger and bend it straight ish,put it into a cordless drill and whisk the shite out of the mixture until it has soft peaks like merangue (?) if it seems a bit thick add more engine oil.

Fill a shutz gun with the concoction and apply over welded areas and underbody wearing a full paper suit.You do not want this shit in your hair or skin,its horrible to get off! johnny had to scrub me down for ages in the bath last ti...........er i mean......

when it cures it will have an outer skin like a custard but underneath it remains putty like,so it never hardens,never cracks and 100% wont allow water through....ive done cars 15 years ago that still have perfect steel under the mixture,works a treat."

Just to re-itterate, this is not my concocsion, its from the MR2 site, so please don't slate me for this!

This does work as a preventer. remember that:
1. Takes weeks to dry.
2. You will never get it off your drive.
3. It is carcinogenic due to the used oil.

I am sure it does but his cars never rot as he can’t drive them due to the stench of gear oil It's not easy finding info on this subject. Manufacturers obviously have their products tested against others at facilities like Millbrook and probably pay a substantial amount for it. The results will be confidential though.

Started pouring this on the samples a couple of days ago



I know it's only a mickey mouse test but a week on and they look like this

Dynax left, Waxoyl middle, untreated right

[Colin Gibson]

so all I need to do now is find a brand new 200sx which has never been exposed to the outdoors, transplant my engine/drivetrain, get it sprayed up underneath with this goo....
then no more worries!

[Si]

I have used stonechip to protect my arches, but not on bare metal. I have used the POR-15 '3 step treatment' (Marine clean to degrease, metal ready to prep and 'convert rust', tehn POR-15) and then covered that in Stonechip paint by Waxoyl - the stuff that is basically a thick tarry goo - this way i figure i should have the best of both worlds. - protection of the metal underneath that should hopefully seal it (the POR15 sets like concrete) and the tarry goop to keep stuff away from it.

Fingers crossed, i'll tell you how it holds up in a few years!

So that's the easy bits (rear arches) done. Next step - the aforementioned sills and box sections, along with the entire underbody.

This is Dinitrol's recommended treatment areas for the S13




Might as well just immerse it

[scimmy ben]

iirc, either the Practical Classics or Car Mechanics tests put a scratrch down the middle of the panel to test the 'self healing' properties

Where did you find that? Can you get the info for other cars?

[Petrol]

I bought some epoxy mastic from this place and happened to mention it was for an SX.

http://www.rust.co.uk/home.cfm

When the paint arrived they had included the data sheet. Maybe they are trying to sell me some Dinitrol

[djlee_dj]

any more results ?

wouldnt mind doing my 14a

I only intend to use the wax in box sections so it doesn’t really need to provide any impact or self healing properties

any more results ?

Yep. What was interesting is that after it had stopped raining for a few hours, the waxoyl covered plate still had a puddle of water on it, whereas the dynax S-50 coated plate was bone dry.

Pics say it all really. Left is Dynax S-50 Right is Waxoyl. Bear in mind its only 17 days ago I started this test.



Pic of the back of the plates to show how much corrosion I managed to achieve Again left is Dynax.

[djlee_dj]

were do you get the dynax ? is it dear ?

same sort of stuff to waxoyl ?

[Petrol]

No it's not expensive. Phone them on 01277 658899 to order.

No it's not the same as waxoyl

[djlee_dj]

is it applied the same ???

how much is it ? how much to do a complete underside of s14a

[Petrol]

At a guess about £40
