The board is getting more attention than ever.
Starting with adding filler with the best tool availible.
Give it a good rough handling and be sure to use a lot of filler to get it in every tiny gap of the foam.
After smearing filler all over the board, I brushed everything to give it better texture than my fingers did, I did it extra rough over the tiles to get them visible again.
Then I dipped the brush in water to make the filler a little more fluid, it had gotten a bit hard since I began and also to brush the tiles again with water to make them even more visible.
I mixed in a bit of fine aquarium sand with filler and water and brushed the rivers with this.
After the messy messy filler part was done I poured fine sand over the board, especially over the rivers.
While waiting for the filler to dry I played a game of X-wing, a tight game with my opponent manouvered very good and was everywhere and avoided crashing with a few millimetres every turn. But the last two turns my ships went bananas and critically hit everything and evaded almost anything coming their way, and the Tie's were reduced to space rubble.
Better luck next time, Empire.
After wiping the floor/space with my opponent I shaked all excess sand of the board and waited for some paint to come it's way, more of that next time!
