Thanks Rokket and Nicolas,
Rokket; It`s difficult to tell exactly the points what i am doing until i reach this result on the wooden deck.
I just start painting the deck with a couple of layers with thin paint of various shades of brown/black/grey,
sanding the deck between each layer of paint.
On the area`s where the wood wears more, i almost completely remove the paint with fine sandpaper.
By the way; this was the first time i used water-based paints, and it worked out great for me.
The hull will be painted with enamels, but some parts of the weathering will be done with acrylics (i am going to try the hairspray chipping technique for the first time).
