If you are referring to the Liberon Gilt Cream, this is one I did earlier.

Gilt creams or 'gesso' usually require several layers and a final laquer coat to protect them whereas gold leaf (as opposed to mock/imitation 'gold' leaf) needs no further protection and nevers dulls.

This mirror surround was coated over 18 months ago and has not been lacquered, and it is in a bathroom.

I've tried Humbrol's brass paint and it looks like the rough (cast) brass plumbing fittings currently being sold, but not the sort of sort of lustrous 'real' brass you'd expect with vintage radio. I wonder how they put down the wonderful gold-coloured finish on the cases of alkaline batteries?

Items like those batteries rely on their surfaces having a reflective silver coloured finish. This is then printed with a transparent yellow ink, producing a bright gold, the colour of which can easily be adjusted in the printing process.

Something similar might be achieved at home by tinting clear varnish and applying it over silver paint, but I've never tried.

I'm doubtful that paint is the way to go for brass, and I'm now beginning to wonder whether brass is the right finish for what I want to achieve My component is currently covered in acid-etch primer which has a flat, pale olive-green colour, and looks curiously right; functional rather than decorative, which I like. But thanks for those websites, which are well-worth having on file.

What exactly are you trying to 'brass' and need it be mirror-glossy? If it is not going to be handled, kept cool and not be subject to weathering - might spray-on adhesive and brass effect sweet wrapper foil (as earlier mentioned, these are coloured inks on foil) suffice?

If you want a weathered metallic brass effect foil, the (still expensive) Dutch gilt (being copper based) does eventually tarnish if not lacquered.

Decoart (USA) make a very good range of metallic paint.

It is available at Hobbycraft.co.uk who have stores all over the UK. They also sell small packs of gold leaf.

Polish to a shine and an orange varnish, just like the cells mentioned earlier?

The part is die-casting with a very irregular shape and with very fine raised lettering. Many thanks for the suggestions, I'll see how it progresses, though as mentioned above, I may change my mind about the brass finish idea. But just for the sake of anyone who checks this thread out for their own use, this company http://www.indestructible.co.uk/ has a "brass dye" product which looks interesting, but as is often the case, a little expensive for a one off application.
