How to – create that aged bronze look

I have always had a hankering for an old style boat signal horn but could not find one that (a) was not chrome or plastic (b) did not look like it should be on QE2 (c) did not sound like a freight train.
So I bought a small chrome one on trademe & being a clever bugger talked to the people at Porters Paints http://www.porterspaints.co.nz about their speciality finishes range – in particular their ‘Liquid Copper ‘ & ‘Patina Green’ products, which if used together recreates copper with the green patination of age. Its used in/out doors on things like downpipes & garden ornaments.  So I think its worth a go, as they say
First step – give the chrome surface a good sanding to score the surface.
Next paint (2 coats) with a vinyl etch adhesion primer
Next step off to Porters Paints for the first coat of ‘Liquid Copper’, looked a little bright but I’m told by the experts to have faith. One more coat then we start applying the patina effect, after the 2nd coat it started to tone down (darken) a little.
We left the horn for a few days & the ‘copper’ darkened even more & will continue to age with exposure to the elements.
The ‘Patina Green’ was then applied & I’m very happy with the end result.
Note Porters Paints are about to launch a bronze finish so I’ll update later on that.
