Painting fence for customer

Today I painted the fence model in 1:1 scale. :) It gave me some experience with polyvinyl paint.
It's kind of liquid rubber. I do not know how you can use it in modeling hobby.
But as my son says: "It's a chemistry that if you eat one teaspoon, you will hit the graveyard ." :)
A thinner to the paint is even worse. 
I dont know, maybe i can use it to make some terrain or dioramas.
