Due to the ongoing over-demand versus supply challenges, but in an effort to continue being able to supply a limited number of these products Monitor Products is currently NOT painting any of our Fresh Water Cooling system products. This will not affect the life expectation of the products, but we do still recommend them to be painted by the customer before installation.
