     Since deformation manifests itself as a change in the metric characteristics of continuum, in the theory of finite deformations, it is then necessary to compare the referential ‵g_ασ and the convective g_ασ metrics. We systematically employ Latin indices in order to refer to spatial components of geometrical objects, whereas Greek indices to point on convective components (only a few instances can be found in the present study) or referential components (additionally, root symbol is sometimes supplied by backprime).

     I'm assuming a well-built building, with clear pine trim and vertical-grain red cedar clapboards. The first step is to backprime the trim and siding. Backpriming is simply painting the back of the boards — the side against the house — with oil-base primer before they are installed.
