Review on 🌲 Eco Wood Treatment EWT1, 1 US Gallon, Long-lasting, Semi-Transparent Silvery Patina - High SEO by Glenn Cho

Upon closer inspection it appears to be just ferrous sulphate available in 50 lb bags for around $30. Smaller bags cost around $6. They don't have that brand name but at a fraction of the cost. Save your money and don't pay them to put a few tablespoons in the bag. Yes, obviously the national parks use it. We all know how governments don't waste our money lol. Do your research before you buy and don't waste your money like I did.
