get galvanised hardware.
Use Stainless hardware
Lastly if you paint them it will come off when the nuts tighten and
eventually rust. I am thinking about what we use to fit tv aerials, badly
plated hardware corrodes very fast and eventually falls to bits as
effectively there is no thread, just the rust holding stuff together.

Hi All

I am restoring a bench where all the metal fixings had rusted. Some joints
have large barrel nuts and bolts and others bolts and inset nuts.

I was thinking of putting something on them before refitting to try and
protect them. I had a few thoughts...
- use something like vasaline but guess the oil would ingress into the
wood.
- paint them before they go in.
- given they are all M8 the rust is probably superficial anyway so only
need to deal with the thread to tighten if necessary at some other point.

Anyone have any ideas on how to prolong the life of this?

Thanks in advance

Lee.
