.Douglas Fir is the ideal timber for this type of signage. It is exceptionally strong and durable as well as being very water resistant. It is very useful in exposed situations where maintenance is difficult. In the past we have had problems with paint creeping up the grain. However we now have a new tough fast drying paint which suits this timber perfectly. This type of timber is perfect for large wooden signage. http://www.sign-maker.net/wooden/farm-sign.html
