Great product for the money

a month ago
I used Thompson clear wood sealer in my privacy fence. The pickets are for so I need a product that would make them last. I live in the coastal mountains, so a lot of weather conditions. It’s been 5 years and the fence barely looks weathered. Getting ready to treat it again. Hopefully it will last another five years.
