rare spares stuff are crap try craig vane sheet metal in Maryborough, we have used rare spare sills and they are not even the right shape or length, i dont  have the address for Craig vane but it shouldnt be to hard to find on the net.

this is an original nasco heater? if so how much and would you have a photo if it is still for sale

Hello mate i am a spraypainter been out of the game for 3 years but still a good hobby the easiest way about going about this would be use a standard colour black/green keep in mind you can only use solid colours whatever colour and and add flattening base i would use a 2 pack system with the same brand flattening base follow the data sheets for correct mixing otherwise it can go pearshaped eg chalky. acrylic systems if you can still find shops that still deal in acrylic would be easier and cheaper to do by yourself as it is a lot easier to spray but a lot less relisient to the elements. any good paint shop should be able to help you out
