Stucco cracks will telegraph through the topcoat and … WebJan 9, 2014 · Conklin coatings require all galvanized surfaces to be “etched” (roughened) first. Most surfaces should be allowed to “weather-etch” by leaving exposed and uncoated for three to six months. As an alternative to weather etching, clean the metal with an acid such as Conklin’s Rust Off cleaner. Retighten all fasteners and secure substrates firmly. jetblue a220 seats
