I remember watching Wheeler Dealers" a few years back and they used this solution that fixes rust. I think it neutralised it or something, can't really remember. Does anyone know what it's called and what exactly it does?

Thanks. It's been bugging me for ages.

As above, "kurust" is what I use.

It's not magic stuff though. It's just better than primer if you're wanting to bodge over a rusty surface with some paint. Ideally you should rub it down to the metal or cut/weld. Painted rust will always come back through in the end.

Someone feel free to correct me if I'm wrong but it just inhibits rust (Or Hydrated Iron-3-Oxide biggrin) by forming an airtight surface and being hydrophobic doesn't it?

There is only one proper fix and that's cut it out and weld a new piece of metal in.I hope thats not on your 355!

Kurust and other magic ointments don't work - end of.

I've always used Kurust but been reading LOTS of good things about Vactan which is a very similar product.

Are you thinking of POR-15?

Ditto, temporary measure though.

Forth railway bridge is no longer being painted. Instead they,

blast clean to bare metal
apply zinc based primer to prevent corrosion (35 microns)
apply a glass flake epoxy intermediate coat providing a barrier (400 microns), and
apply a polyurethane gloss top coat (35 microns)

This system was designed for offshore oil platforms and is designed to last at least 20 ­years. Maybe up to 40.

You do not own an mgb do you? wink


Edited to add: If the part is small enough you could remove it and leave in an elcetrolyte bath.

If it was the mx5 episode, I`m sure he said it was a milky liquid that turned the rust black, which sounds a bit like Granville Rust Convertor (and vactan too, after googling it, I suspect they are similar)

This works quite well, I have used it in the past.

If the parts can be removed, it's best to get the soloution rather than the gel.

Vactan.

Nothing else comes close. Quite cheap off EBay, and a litre goes a very, very long way. I use it at home for treating agricultural machinery that has to live 200m from the Irish Sea. One run of Vactan annually stops the machinery rotting away - untreated you can lose plough bolts to rust in 2 years.

I spray it on with a small touch-up sprayer, then sometimes lash on some watered down Dinitrol for the machinery that's regularly used.

Well, I have a topic active right now asking about it, but having done my reading around the web, POR-15 seems to be the very best approach.

Haven't tried it yet, but unless someone can suggest something else worth using to cure the beginnings of some wheel-arch rust, I'm going to order their 'starter' kit.

I've used Kurust but I think (from what I've read) that the POR-15 is in a different league. Perhaps...

Jenolite has gone bust, and it's just Vactan anyway...
