The only way to remove rust is to do just that remove the rust!

Use a grinder and grind back to clean metal. Then check there are no tiny pin holes. If so then you will have to remove the affected area and weld in new metal. This however isn't always enough!!

I speak from experience. Working in a body shop you get the odd old banger but worse than that are the rich boys with really old porkers and prancing donkeys. The cars can be worth a fortune and they get charged a fortune aswell so you have to do a shi1thot job! Very time consuming and boring!:rolleyes:

agree with jimbo, most rust starts from behind the metal, so removing the face and spraying is just covering it up, not curing it. Get the grinder out.

I've used kurust and in my opinion its crap! took it right down to bare fresh metal, used 2 coats, primed it, spayed it and in 6 months it came back faster!!

On the mini i used 'red lead' if you can get it, it works a treat.

Well so far I've only used kurust on a few bits and bobs and personally so far I've had no problems with. Don't forget that you're not supposed to completely remove the rust with this stuff. it's applied directly to it. It seems probably best not to use it, okilydokily. As i said, it's only surface stuff and am not too worried about it, but i want to sort it before covering it with the 3M stuff which is the dogs danglies.

i must admit though i had this chip on the roof of my cav, it was there for years surviving with only a blob of kurust on it.

trivia time: did you know that rust is the same chemical reaction as fire.

I would not bother with either. I wasted time trying that stuff. There is no substitute for removing the rust. Next best thing, which can last years, wire brush/grind/sand most of the rust off, use a high zinc primer, Davids, or whatever. Look at the zinc content on the tin. Many are low zinc, as zinc is toxic. Let it dry for 24 hours, perhaps 2 coats, then prime, paint and underseal, etc.
You must paint on top of the zinc primer, as primer is not waterproof. Zinc really does protect the metal underneath.

Jenolite is the best. I have used both.

Kurust forms a coating which allows the rust to form underneath again without you knowing, Jenolite doesn't.

One day I'll buy a car that doesn't need de rusting every month :mad:

Always found Kurust o do the job myself. But if you leave it at that then it'll just come back, Once you've rubbed down and kurusted then you need to seal it. The best thing for this if it's hidden is smoothrite. No air-no rot. If it's anything more than general surface rust it's best to cut it out but then seal the new metal before it starts to rust as well.

Yeah it will be hidden as it's underneath the car. The genral plan was to overhaul everything underneath, rearbeam off etc.

Generally I was looking at:

General rust removal - all loose
Rust treatment
Anti-rust paint
3M Bodyschutz - whole of underneath on chassis

i've used jenolite twice, one treatment lasted 2 years and still looked spot on when the car was sold, rust never came back.

BUT, i got rid of all the rust with glasspaper and used the jenolite to seal the metal. i used it as a prevention not a cure.

i'm sure the zinc thing would work better, (preferential corrosion), but jenolite works fine.

Did you know that you can use zinc as a sacrificial metal if you have a leak in your car??

If your boot leaks chuck a bit of zinc here there and everywhere and gasp as it corrodes:eek: :eek: :eek: and your boot floor doesn't:D :D :D

Yet another boring tip from the bodyshop trade..........

I have tried both of these and would say that Jenolite works better. HOWEVER I would say that neither works as well as Rust Bullet.
As this thread is 7 years old, the author should by now be able to give some good feedback lmao
