Great product

Bought 3 gallons for my small patio and fence. Used it on my parents 18’ x 36’ multi level deck. We do this once a year. Added my mother in laws deck with another gallon plus a neighbours 20x 24 deck for another gallon. You should sell it in 5 gallon pails.
A friend asked for help and was using Olympic and it was not even close. No penetration, terrible coverage.
Yes, I recommend this product.

Great product for the money
2 months 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.
