bathroom window bead rusting - big job or little job?

[rblaa]

Hello. I am trying see how I can fix a rusting window problem in my bathroom. I am not a handyman usually (am a stressed out software guy), so jobs like these usually get me all worked up.

You can see how things are in these pics:

I am hoping this is something I can scrape or sand off, then paint with tremclad and plaster with polyfilla or something. Or do I have to dig out the bead and replace it?

Any advice is appreciated.

I also know this bathroom needs a fan, but that's another job.

I would remove the bead and replace it, knock off the finishing plaster a couple of inches either side of the bead. Fine coat corner bead you can get from B+Q for a couple of quid.
Reinstate plaster using easi-fill which is easier to sand and blend in as opposed to gypsum plaster.

You can clean off the rust prime with an oxide primer then gloss and then emulsion. Or if you replace use either plastic of S/Steel bead.
You then need to think about ventilation since you should not have condensation dripping down the walls.

Thanks for the help.

It turns out that the fan issue is deciding things for me: I need it to fix the moisture problems, and if I am hiring someone for that, they can fix any window and plaster problems as well.

So, while this is perhaps a step back for the DIY idea, it's solves my practical problem, albeit at a money cost.
