The sail area is where the match numbers are, so the touch ups will be seen at the conclusion of each game. The area is not backlit, so I'm "getting away with it". I brushed the jo sonja paint on - a little too thick - and two coats. I might TT the repainted areas depending on how it looks. I thinned the paint so it could be brushed easily.
What do you use to thin the jo sonja paints with, is there something special to use?
