Painting Radiator & Treating Rust

[topgazza]

I have a couple of radiators that have the usual rust spots on the bottom that have lifted the paint. i have rubbed them down in those areas and removed any loose material and have a fairly smooth sanded surface. In the past I have treated these with red oxide paint and then over painted with a proprietary white radiator paint.

Is this a good method ?

I used to paint rads with gloss white but figured radiator paint is designed for rads and the heat. But I suspect it makes little difference and a good Dulux type white gloss will do just as well.

I would hope that using red oxide would prevent or at least delay any surface rust coming through.....

Pretty much do as you have in the past, only thing I do extra is to clean the rust off with some white vinegar, there are loads of different products for this but I find the vinegar does very well.

A big no from me as regards to the gloss, it will yellow pretty fast.

If you get good results with the way you normally do then stick to it.

Thanks. I have a big 5 litre bottle of white vinegar for limescale so I've already sanded to bare metal and cleaned the rust area with that and gave it a coat of Red Oxide paint on the bare metal. Its not much just areas at the bottom of the rad. I have read comments about rad paint that aren't great but I find it's OK and it does keep white for a fair while so as you say I'll do that.

I don't think there really is a perfect product for repainting them, could use water based satin but its hard to get a brilliant finish and its not as durable.
