Is Kurust any good? www.hammerite.com/uk/products/ps_kurust.html"Converts iron oxide to stable iron complexes" I remember plastering my 1303 with the stuff, and it never seemed to rust back through but i don't know if it actually did any good... Obviously it's no replacement for new metal welded in but as a stopgap, on bodywork, does it halt the rusting to allow repair on top or is it still better to cut out the rot?

i used it today, see retrorides.proboards29.com/index.cgi?board=general&action=display&thread=1147432005a mate used a similar version called hydrate 80 to etch primer his bare mk1 shell. it hasnt rusted yet so i assume it does well. i pretty much got out all the rust possible first then applyied it. its water based i think, which makes no sense applying water to steel in order to stop rust ;D it does go a ratehr satisfying black colour that seems to give the metal a 'rust free' look to it ;D.

From experience, I can quite honestly say Kurust is total rubbish.

yeah it was your thread that reminded me of the gallons i went through i guess if it's all scientific with formulas and diagrams and wibbly bits of stuff then it must work... hammerite is a pretty reputable firm. Had it been £2.99 a bottle off eBay with a description of "Magic Rust Remover! L@@k!" I'd be more skeptical. Samage - is that from experience? Or it's rubbish in that it's technically a load of curse word and scientifically can't work?

either way, its all getting red oxided, then a good seeing to with some waxoyl.
i didnt use it to magic rust back to steel, i used it to stop the tiny bits that i couldnt get too turning into anything worse.
I'm slowly reclaiming my car from the clutches of iron oxide ;D ;D

ive applied kurust to my supra on tiny rust scabbages.. seems to be working fine so far. yet 10months back when i applied it to my e30 it only seemed to make matters worse(hid the rust in black and continuted to rot)...don't ask me why i used it again.. (probably cos was too lazy to buy anything else?!?!) but on the supra seems to be ok.. so far.
so technical summary is
kurust loves the toyota kurust hates the bmw

youll probably find that it didnt get down to the rust that was behind and therefore left it free to turn nice and regular steel into brown rot. i sound like a PR for kurust ;D id only use it on tiny bits or where its pitted, anything else required proper graft to stop it happeneing again

i've used crust a few times, it always seems to do the job. I tend to paint on a precautionary coat of krust before painting a surface with primer.

As far as I could see if you treated it like primer, brush the rust back as best you can then apply to bare (half decent) metal it would stop it getting any worse, but once metal was going rusty it wouldn't stop it rusting from the inside out, just stop the outside from becoming obvious again...

I find it converts the top layer of rust & seals in the deeper rust rather then convert it all.
Its better then using nothing but i think there are better products out there.
I used some on the bodywork of the mini and it turned all the rust black which looks good but a soon as i sanded over the top it just sanded the black coating off and i was back to square one. That said i did a bit in the boot of the fez back in december and it semes to have helped slow the tin worm a bit!

I guess these potions of stuff can only penetrate so deep - so although the surface rust may get treated - rust deeper in the metal can continue to grow Thing is, these 'Kurust' type products may work quite well when treating some minor rust patches on a nice flat sheet of metal where it easy to see the extent of the corrosion & its even easier to get a good cover of paint/primer over the top - when it comes to the complex curves & joints on a car its a different matter, epecially when its these areas that collect water & dirt & are the most likely places of a car to rust BTW I've had some minor success with both 'Trustan' and 'Jenolite' - As mentioned above, I normally apply a coat of Jenolite before re-spraying any area that i've bare-metalled as a precautionary measure.

I suspect with those products you need to work it right in with lots of wire-brush action for it to do its stuff properly.
Alternatively a spoonful of Kurust in a double vodka + lemonade makes a sharp and refreshing (if slightly alarming) opener to one's weekend.

either way, its all getting red oxided red oxide primer isnt actually any different to normal grey primer anymore, it used to contain lead and all sorts of wibblepoo back in the day which is why it stopped rust. Apparently.

I use some stuff called Metal Ready from frost. Its like an acid that you spray on at regular intervalls and after a while it starts to actually wash the rust away. You have to use it over a long period of time for it to do any good though. What i tend to do is just keep an area wet while i'm down the workshop and after a few days it takes it right back to clean metal. I'd only use it on surface rust though. If the rots deep then just cut it out and replace it.

Kurust I tried years ago and think it was rubbish, sorry.
Correct! It used to be known as 'Red Lead' but that changed sometime in the early 80's ...shame, it was damn good!
