Good sealant
The best sealant that I've tried. This said, where applicable I prefer to use urethane lacquer, since it looks much better.

Best VALUE
I had a new privacy fence put up this summer. I have always found that Thompson's products are worth the extra cost. They really last and perform well.

Great stuff - doesn't smell or go yellow
Really good stuff for waterproofing pinewood and hardwood furniture. Not too messy to apply and doesn't yellow. However it doesn't last as long and needs a regular recoating after exposure to sun and rain.

Taking care of my wooden fence in the sun.
What I didn’t like was the price went from $19 to over $30 a can.

This is a great product, which is why we were ordering more. The description is criminally incorrect, though. You get 1 can, not 4. Fortunately, the shipping was super late and was pronounced lost by the seller. It showed up days later - but only 1 can. They're half this price at the store.

C’était le bon produit mais pas la bonne quantité

The write up clearly states package of 4. I paid $100 and recieved one can. Went to local hardware and picked up 2 more ca s for $29 each. Lesson learned.
