The manufacturer of Thompson Water Seal recommended that you use their product with a plastic sprayer with a brass wand, such as our Chapin Premier sprayer. There are no concerns about it eroding any of the seals inside of it. Once you are done with the product, it is recommended that you run mineral spirits through the sprayer and then water to clean it.
