A method for applying a protective coating to a surface. The adhesive dressing of the invention provides extended wear time for the dressing when it is applied to wounds. The photovoltaic attachment system comprises of a grid of photovoltaic panels mounted on top of beams that are attached to the walls around the roof. The multispectral imaging system and method is suitable for use in an industrial setting, such as a meat processing plant. The spacer assembly slides over the posts when the posts are inserted through the corresponding holes in the helmet, and frictionally engages the outer surfaces of the first and second posts such that the helmet is disposed between the base and the spacer assembly.
