How long will the product stay effective after opening? A one-gallon container is a lot of material for me. I suspect that I would only use about half of it the first time and the second half twelve months later. Will the product still be effective?
You can expect the product to stay effective for at least 3 years from the date of purchase if it is stored properly. Keep out of direct sunlight and out of extreme temperatures.
