How to paint traction engine boiler

It has been a while since you posted the query but my neighbour painted his miniature steam locomotive, 5"? gauge, with IIRC International Paints 2 part yacht varnish system and that seems to have worked well. It was brush painted as recommended, as spraying was not advised due to the chemicals, and then flatted and lightly polished to give the paint appearance of working engines which he had grown up with seeing on the Somerset and Dorset railway. It has been done now for 6 years or so and seems to be holding up well and is mixed metal construction. I can ask for more details if required.

boiler? The hornplates will get bolted on soon, so that part of the boiler will never be seen again, so protection is the priority. Plus most of it ge ts covered in cleading, only the backplate is really visible, any advice on finishing the backplate? for the 4" Burrell I am constructing the boiler has been painted with Mastercraft high temp semi gloss, in black. Obtained from T & R Williamson, Ripon North Yorks. As the smallest supply quantity is 2.5L a lot of other bits are painted semi-gloss black!

I use Halfords High Temperature Enamel for the smokebox on my 7-1/4" loco - works fine.
