Methods for preparing and using at least one protective coating on industrial articles and storage systems are disclosed. In one example, the industrial components are dry storage cannisters for spent nuclear fuel or other waste materials. An example method for preparing at least one protective coating on dry storage cannisters for spent nuclear fuel and waste includes dissolving a dispersant in an organic solvent. The method further includes adding a polymer-derived ceramic (PDC) to the organic solvent and dissolved dispersant to create a pre-ceramic solution. The method further includes applying the pre-ceramic solution on a metal and/or alloy of industrial articles and storage systems such as the dry storage cannisters.
