I've done a small search and found out some cost of goods info. Fusalade II-.75oz per gal covers 1000 sq ft. At $64.95 a quart it works out to $1.52 per gallon or .75 per ounce. Surflan-3oz per 2 gal covers 1000 sq ft. At $299.00 per 2.5 gal it works out to $2.80 per 1000 sq ft. These are just cost of goods. Does anyone have a database of items like this? The price is variable I know, but if we had the other data we could plug the price in and have an accurate database of cost of goods to project estimates with. I'm posting here because this forum is the one dealing with chemicals. I know it's a back office post but, I feel like it will get more exposure here.
