Signs and Symptoms of Psoriasis. Psoriasis is a common autoimmune skin disorder which occurs when the skin cells replicate too quickly. The skin produces new cells at many times the normal rate, creating inflamed, scaly and red patches of skin, called plaques, where the old skin has not shed quickly enough.
Galvanization is the process of applying a protective zinc coating to steel or iron, to prevent rusting. The most common method is hot-dip galvanizing, in which parts are submerged in a bath of molten zinc.
1 Alkyd/oil paints that are applied to galvanized metal will adhere initially, but will quickly fail. 2  The zinc of the galvanizing will chemically react with the alkyd binder of the paint, creating a âsoapyâ film (saponification) on the galvanized metal and causing the coating to peel. Instead, use a water-based cleaner/degreaser to clean a galvanized surface. 2  Most acrylic coatings will adhere directly to cleaned galvanized metal. 3  A weathered galvanized surface develops a layer of white rust, which must be removed to ensure good adhesion of the coating.
