We live in Northeast CO and put up a wood fence using virginia white oil stain from Ace Hardware thinking that this would be a better choice than using paint. Every two years we have to add another coat of the oil stain because of fading and having black come through the boards. This is a very expensive project to do every two years and also takes way to much time. We do apply with a paint sprayer. Is there anything else we could use that would last longer? The oil stain cost approx. $23.00a gallon, we end up with $300 every two years to keep the fence looking nice.
