Anti rust potions ?

================================== My experience with 'Kurust' is that it's far less effective than either 'Jenolite' or 'Naval Jelly'. My preference would be for Jenolite but others may have different experiences.

I agree. However, I only use after getting as far back to decent metal as possible. For that I use a drill mounted wire brush or just soak the rusty part in battery acid overnight.

I was reaidng the hoto use krust it says all you have to do is brush it on and 15 mins later problem solved ?

the size of rust I have i what is called surface rust according to a friend about half the size of a 5p piece. On he rear wheel arch where there was a repair by chips away.

I was hoping that I could just brush on that stuff and then apply some topcoat (says no need for primer etc) and clearcoat with the touchup pens I have ?

or have Iunderestimated the power of rust.

================================== Rust is a bit like an iceberg - what you see isn't what you get. If you think you've just got a small visible area then try the Kurust and see what happens. You may be lucky or you might be providing a nice cosy environment for the rust to travel under the paint.

Yes. Kurust and the likes never soak in far enough to kill all the rust, so you end up with a painted scab with the rust getting worse underneath it. If they're only 5p sized patches, you could try scraping away with a screwdriver until every trace of loose rust is gone, then applying the magic potion of your choice. That should keep it at bay for a while.

Thats what I'll do sounds like top advice. Hopefully that will send it on its way.

I guess halfords should stock it.

Thank you cicero and willy for the help. *thumbs up*

I would scrape as suggested, then use Jenolite (or Phosphoric acid, which is what Jenolite is) and rub it in with steel wool.

This topic has been dealt with about a dozen posts down. I have never had any long lasting benefit from any of these patent products. The only thing that works 100% is free! Old engine oil.

You mean I should smoother my rust patch with used synthetic oil after my next oil change ?

ROFL. Reminds me of when I took an old Mini in to have the rear valance replaced following having an idiot drive into the back of me.

"It's a bit rusty mate"

'I know'

"We'd have to cut forward to good metal"

'Ok. How far would that be'

"The headlights".

You've certainly over-estimated my ability to tell what you're saying. Has the concept of typing slower or proof reading what you type occured to you?

If it's on the outside (painted side) then you may not want oil there, but if it's unseen, then yes. You'll not see any rust where bearings leak oil and grease around them on machinery. And if there's some crud there, don't take it off. It helps to hold the oil.

================================== One of the better examples then. A bit of body filler here and there and good for another twenty years.

James explained :

Yes, oil is the only thing guaranteed to stop rust in its tracks. It will soak through any thick oxidised coating right down to the metal. If you can get to the rear of the rust on the panel blather it all around the area.

The only anti rust potions that work in my opion are as follows:

1) Get rid of the rust, all of it. Get really really rid of it. 2) Acid etch primer. Wear a mask so your lungs work after. 3) Dinitrol.
