Thanks guys. Some of the pics i looked at, there seemed to be some fadeing on the deck. And i checked a couple of builds where they had done it as results of the salf spray, so that made sense.
Steve, i use the base paint, which is enamel, and mix with a drop of white oil paint, the 2 mix really well. That way you start with the right base but still get the advantage of oil paint. I did this in 3 stages going slightly lighter each time, trying to focus in areas of heavier footfall and well as were the salt spray might be more prominant.
I air brush it. I have not been useing future on my builds for a while, useing Alclad aqua instead. But i decided to use the future on this one.
