Can I apply zinc spray directly onto rust?

We have galvanised gates and railings but some of the fixing bolts were not galvanised or have become damaged and we have a bit of rust on them. Can I apply zinc spray directly onto the rust or will it just flake off? In the past I have only ever used it on bare metal. I know I should really de-rust first but it will be a heck of a job to remove all the fixings, especially the gate hangers.

Have a look at Jenolite https://www.jenolite.net/ It converts rust to metal. I think it is only a fiver a pot. I used it many years ago on something (I cannot recall) and it worked really well.

Don't know if its the same stuff, but Ed China uses that when he fixes cars, so if its good enough for him........




Bearing in mind he does "put something" (filler in this case) over the rust killer stuff.

Yes, that is the type of stuff. Just go over it with primer and paint.

Well it will be zinc spray as the final coat since it needs to blend in with the galvanising.

If it isn't too bad just give them a good wire brush and then the cold galv. If it is bad use the rust converter then cold galv....

Build up the cold galv in a good few layers, especially if it's a cheaper brand.

Have you done this yourself? I was worried about the cold galvanise flaking off.

We use loads of cold galv at work, modifications to galvanised metalwork, in the repair or damaged galv coatings from new...

It doesn't flake off as such, once dry if you rub it you may have a silvery residue, that's about it. After a good while you may end up with a slight bleed of rust.
The thing is with zinc coatings is its sacrificial.

Some of the cheap ones are barely any more than silver spray paint.
Zinga is one of the best.

A blast from the past. We used to use that to clean the gas plugs on our SLR rifles back in my army days.

The FN L1A1 rifle was a great gun, very accurate but a bit cumbersome in combat. The SA80 once sorted out appears to be a better gun but the FN is still a good gun in my opinion.

We were one of the first battalions to try out the SA80 in 1987. I don't think our armourer slept for about 4 weeks. I don't know what improvements were made to it but back then I didn't rate it much. Still prefer the 7.62mm
