Rust conversion chemical.

[chris-red]

Can anyone recommend one? Ideally a small bottle as I only need a little bit.

Small bottle? Got to be Kurust then.

Linseed oil works extremely well, I've used it on my ZRX (bolts/nuts mostly) and they've all developed a chocolate-coloured coating with no more rust.

Phosphoric acid works too (the active ingredient in most anti-rust products I believe).

The cheapest of the shelf phosphoric acid product I have ever used was brick cleaner, normal cost is 20 quid for 25 litres and it works wonders on stainless steel downpipes, gloves and eye protection are recommended when using any phosphoric acid products.

If you can hold off until tomorrow I'll check at work, I'm pretty sure we have bottle of that stuff which never gets used, if I can find it I can run it down to you tomorrow evening.

ive used this rust-ins stuff with good results https://www.ebay.co.uk/itm/like/121219049129?limghlpsr=true&hlpv=2&ops=true&viphx=1&hlpht=true&lpid=108&device=c&adtype=pla&crdt=0&ff3=1&ff11=ICEP3.0.0&ff12=67&ff13=80&ff14=108&ff19=0

Citric acid crystals from Wilko about 1/4 of teh box in a pint of water. This will work if you can immerse your rusty thing in it and scrub every few hours for a day or so. Cheap as chips. Otherwise you will need a gel compound based on phosphoric acid as mentioned..

[chris-red]

I'm not after any kind of cleaner or acid, what I'm after is something like the first 2 suggestions. A product that chemically alters the rust back to solid metal.

The oil tank on my TDM was hit by something a while back which damaged the paint. I ignored it and on closer inspection recently I noticed a 10p patch that is really corroded. I know from experience removing the oil tank is a cunt of the highiest order so I want to fix it in situ. The rust looks bad enough that I'm concerned about going through it with a Dremel/wire wheel. So I figure brush off any loose bits apply this stuff. Maybe a dab of areldite/chemical mental then a coat of hammerite to seal it up.

C_dug if you have something like that at work I can nick a small amount of that would be great I don't need a lot at all!

Brick acid is hydrochloric acid. Will remove the rust, but will leave it exposed for further corrosion.

Linseed oil as Hetzer suggested would inhibit rust. It is a drying oil, used in oil paints. I use flax seed oil (same thing, just food grade) to season my cast iron pans, albeit I bake it on, should still work if left to dry. Although good luck painting over it.

The stuff OP was probably thinking about is a phosphoric acid based rust preventer. Iron III oxide plus phosphoric acid becomes iron III phosphate plus water. Iron III phosphate is the black stuff that is claimed to protect the area from further rust... I've never had much luck. It is a thin and weak layer that rubs off and rusts again, prob works better on very rusty stuff with a thick rust layer. Again, it interferes with paint.


EDIT: read OP other post - I thought it was rusty fixings or something. So... I'd JB weld and paint. Or remove, replace/weld and paint.

Oh and smegballs - rust ---> iron can be achieved with electrolysis, not much help to OP of course .

There are a number of chemical gun blueing products available that might be appropriate for some surfaces that need corrosion protection but cannot change significantly in dimensions, else use appropriate paint.

I've used Kurust on lots of bits of slight corrosion on all my bikes with good effect, not sure what it does but it seems to halt any further rust and leaves a better finish on what rust was there that you can paint over, other advantage is it comes in small bottles with a brush in the cap and you can get from Halfords for not much money

C Dug has a acquired some stuff from his work for me. So lots of karma please! I'll post some pics of the problem and finished result.

Forgot to get pics but the stuff worked great despite being 7 years out of date brushed the crap paint and surface rust off the chemical turned a anything left a dark blue colour and it went solid. A coat of hammerite and it's good for another 12 years.
Massive thanks to C_Dug
