That's not a bad price for two gallons, can you share a pic of the label once you get it? I used to have an account with them years ago and from what I remember, the cooker paint wasn't too bad. Just they never had it in stock.
I've been using Rustoleum for years now due to instant availability, and best value for the dollar. But I've been trying to find something in a higher gloss that will give better stain resistance and hold up to the Florida Sun better. House of color had something promising, but is $90.00 a quart.
