How to remove a bath drain, and bath paint recommendation

[tonton]

I managed to remove it. I tried penetrating oil and a lot of time, but ended up resorting to a grinder and now I need to replace the threaded waste.

Will this shape of recessed hole in the bath accept a standard new style of fitting, or will I need to look for something particular? And/or use putty which looks to be the case on the old fitting?

Yeah - the bath waste hole should be a standard and would normally accept a standard 11/2" bath waste with a ~70mm wide top flange.

Go easy with the bath enamel and rusted area as the worst thing would be to clean it all prior to touching up and then create holes where the rust was, though in saying that maybe best to know if the rust has penetrated right through or not.

Thanks. The rust doesn't seem bad, just surface level. I haven't decided on what paint. It seems like the bath repair kits are aimed more at filling chips and dents, so I might be better off just buying paint separately.

I would firmly suggest you use the proper stuff for the job, rather than some random paint, if you want it to last. Buy some rust killer, phosphoric acid first, and apply that all over the area, after scrapping any loose. That will turn any rust into a more solid black colour, which can then be painted. Next you paint the entire black area, with a resin based metal bath repair paint. That will give you a good, sound, smooth surface, to allow for a good seal with you new plug-hole.

Car accessory places, will stock the phosphoric acid.

The right paint (and acid before) sounds good. I was thinking I don't need the epoxy filler that comes with bath repair kits, just paint. But maybe smoothing out the rusty area with the filler before painting will give a better result.

The rust needs treated first before anything. it needs a wire brush to remove as much as possible the use a rust converter before anything else to reduce the chance of it returning.
