Fence Post Fix Foam 23.8 oz

I was thoroughly disappointed. I bought enough.I thought to do twelve post. Fence post which are 3 to 4 foot deep. The product barely covered 1 and 3/4 feet, 2 and a 1/2 of the 12 to do one post. The calls for this versus concrete Is four times as much?Maybe five. In summary, I would not suggest buying this unless you want your post to fall down. Or you've got enough money to spend six hundred dollars to do one section of your fence. I have eight unused bottles.If someone wants to purchase them for price.
