just been looking through a corsa (a) site and found this

Before the lacquer was applied, the body was phosphated and a rust protection in 8 steps was done. A PVC underbody protection was applied after the paint job.

I think the shells were zinc primered or something like that aswell.

MK1's made in Spaim (?) had the best rust proofing

im pretty sure the second pic they are RHD cars, possibly english.

little known gm fact..... opel specced their cars with the rust proofing treatment back in the late 70's, early 80's.. vauxhall didn't until rustproofing became an issue with ford & vw etc..

Nah, they're spraying on salt water to help start the rust process which was a 100% certainty.

They were all made in Spain, but the early mk1 was made of english steel rather than spanish, which seemed to rust a lot slower.

if they were rust proofed it was cack when i was 19 i had a 5 year old sri and the front crosmember had to be replaced because it had rusted through

Prob is the sealant that was sprayed on the under side isn't very good. Nor was it sprayed all over the under side. There are huge gaps in it.

Nothing was really put in the chassis either...

As was the rest of the spraying. There where also alot of water traps built in. So they hold water and rust out..

Is they where like new cars and where dipped, they would have lasted alot longer.

At the end of the day nothing will ever stop rust. even the newest cars with the better quality treatment.

Renault Clio's, do this bad aswell, the worst are Peugeot 206's though, they rust worse than Novas, especially behind the bumpers, sills and wheel arches, the early ones (Y reg etc) are allready appearing in scrapyards because of rust issues

Ford Ka's are also truly shocking

I think all the RHD cars were built around mid-day when the Spanish factory workers were on siesta. Eh, we screw the English pigs in a few years, pah!

y reg is almost a 10 year old car now though so classed as a banger in my book just like my veccy gsi

rear beams were made just after siesta, with a few sangrias in there belly no 2 beams are the same lol

very true, i look in the local paper every week at the 'bargin basement' 55plates and the lowest price car was about £4k lol

lol thats well true!! thats why nova's had such bad tolerances lol!!

Oh really...

Make them out of aluminium, that might work lol

Except that Aluminium also oxidises. :wtf:

But not in the same way as iron, it actually oxidises instantly as it's a lot more reactive than iron, and the oxidised layer protects and seals what is underneath.

Galvanising works in a similar way, steel gets coated with zinc which is much more reactive but doesn't corrode away in the same way as steel does. It'd be like having a few mm thick galvanised layer, instead of microns.

Still oxides. Which will lift any paint.

whilst we're at it, can somebody please explain to me why people think painting something with primer paint will protect it.....i read it on here sometimes & loads of times in classic type car mags....unless i got the wrong end of the stick, i thought the whole concept of primer is to get a decent key for the topcoat & it is actually porous...... and it is actually a decent coat of top finish paint that does the majority of the rust protection, by keeping the water out.. stonechip paint simply does what it says on the tin, by protecting the top coat from stonechips...

Benn

^ I've said it a few times, that primer is porous and shouldn't be left out to get wet.

But you paint onto the oxide, and it then doesn't develop further and lift paint... same as galvanising, and is why galvanised shells last so much longer.

It is a completely different corrosion process to iron corrosion, similar to surface rusting, but it's instant, you then paint on top of it (think hammerite onto a surface rusted gate?) and it then doesn't develop into the full blown corrosion that steel does which lifts paint and makes it crumble away. They are actually 2 different processes, and I did know the names of them when I did the exam last year, but i've since forgotten lol

iron & aluminium also electrolytically react, so they rust from within.. look at a discovery or old landy...

I was holding back with that point. lol

MK999
19-12-10, 02:04 PM
I'm not sure of your point/relevance? Not many places in a car they're going to be soaked in an electrolyte and have a current passed over them? Also no aluminium will ever rust, what we know as "rust" is iron oxide.

mowgli
19-12-10, 02:18 PM
ok, i'll put it simply... put some aluminium next to some steel, and on a chemical level, there is a current produced, like a battery. then the iron oxidises & expands (as all iron does), and the aluminium goes brittle, they become a tangled mess of oxidisation. ask anyone who has owned an old discovery or rangey or landrover, which have steel & ally construction, they rot like hell from within.

if you build a car from aluminium, there are going to be lots of places where the aluminium simply isn't strong enough, like hinges, mounts, serious structural points etc. these will all oxidise from within.

Galvanic corrosion... only happens in direct contact though afaik, so there are ways around it.

The main obstacle to the comment I made (in jest :p) is aluminium is just more expensive to buy in and possibly more expensive to make panels from as it tends to work harden a lot easier than steel (which has fatigue cycles in the millions in it's elastic region and carries on this trend into the plastic region of deformation.)

However we can get back to the light hearted thread if you like lol
