CONCLUSION While the process known as selective, brush plating was emphasized in this article, other portable processes such as selective anodizing and selective electropolishing are widely used in industry as well. Selective plating is a viable alternative to tank plating and to other processes such as thermal sprays when deposit thicknesses of less than 0.035��� are required. It is a process that lets you apply a wide range of localized deposits and coatings either in the shop or out in the field with very accurate thickness control. Selective plating is a flexible and reliable process for OEM and repair applications. 445
