80's toyotas vs 90's toyotas RUST

[Caveman]

IT IS NOT FISH OIL!!!!
There is difference between metal composition.
My ST165 rusts like lada on salty roads, while my AE101 does not.
As usual ST165 had rusted floors (right trough) so I used piece of spare guard of AE101 to fix it (we gas welded the holes so any "fish oil" on AE101 metal surface, would be cooked off), I was lazy (CBF condition) so I did not painted the welded place (naked steel) straight away and was driving in rain like this for a few days. Basically it took 1 overnight for ST165 steel to rust, while AE101 remain shiny for weeks (that is right I wire brushed the metal surfaces so there was no chance for fish oil to remain, not that manufacturers use fish oil - paint does not stick to it anyway). It also rules out galvanisation (it would be bitch to weld with gas welder). So my conclusion is that "new" steel contains more chromium (or other metal that creates non porous oxide layer on surface of the steel).

Also it is not sea travel that affects new cars, it is the salt on japanese roads, that they put in snowy regions of the country.

oh damn do you think a zinc rich primer or similar would help with rust? Ive thought it might be the steel used but was never sure. This would mean my aw11 is doomed for constant rust repairs

Dylan what you need to do is pull EVERYTHING out of the car, and have it as a bare shell up on axle stands. It wont help with the rust, but it'll make me feel better.

seeing as its relevant. my aw11 ... well rust and yeah
if i was to get it resprayed would it still come back because of the primer?
would it be worth the extra amount of money taking it back to bare metal to prevent rust in years to come?

would be paying someone to do it as well.

baha you would like that wouldnt you, then I can sit in it like you and pretend to be owning up the nurburgring.

hmmm considering taking it back to metal then painting the whole thing in cold galv

Could get it powdercoated?

Dude, its that sort of humourous outlook that makes me wonder why I don't get on the piss with you as much as I used to hahaha

where is the rust, how bad is the rust? ie, are we talking about actual rust holes and actual corrosion of the metal, or just little specs of surface rust.

You need to neutralise the rust reaction, using a rust killer or rust convertor - that will stop the current rust reaction dead in its tracks, then apply a means of rust protection/preventative such as fish oil if its out of sight (ie inside the doors/guards/hatch etc) or prime/paint over it if it's on the outside.

Most of it is just surface, for now, it's bubbling through the relitivly new paint though (2 years old) There is two holes behind the rear bumper at the sides. but thats not too majour. Both the a and b pilars are getting surface too

It's because I've been avoiding you, ever since I traded your strut brace for some magic beans.

PM sent!

Which, might I add, didn't work...

I've got some rust on my AW.... (Surprise surprise) which is at the middle of the A pillar on both sides and at the bottom of the A pillar on both sides, and a small bit on the rear quater at the very back/bottom of the drivers side.

Got a quote to have it cut out and replaced by a professional welder type person, just about gave me a heart attack....


$300!

Of course, he's a busy man, so I'll have to wait, but thats ok, I've got Dom Toretto shipping me over night parts from Japan thats taking a few weeks.

All AWs rust, mine's been in for rust repairs a couple of times. First time for where some muppet had left primer sitting over some half-arsed rust 'repairs' for ages and the second time was from a leaky washer bottle in the frunk. I got rid of some rust in my Rona the other day with a wire brush, sandpaper and that rust killer stuff, time will tell if it'll come back and frankly I don't care if it does). The bottoms of the doors and under a mudguard rusted out on my old Corona too. Rust repairs are usually dirt cheap if you catch them early anyway.
