Abstract
The present invention is directed generally to building tools that are high quality, durable, and in some case lightweight. For example, a mastic flat box may made by forming multiple sections into a single integrated piece by, for example, an extrusion process so as to reduce manufacturing cost and increase the structural durability of the tool. The mastic flat box may be made in such a way as to allow for easier assembly, operation, and cleaning. Further, mastic flat box may be made, at least in part, using a material including magnesium to reduce the weight of the tool. Still further, mastic flat box may be made using one or more protective coatings for protecting various metals against corrosion, for example, using a high impact coating such as paint covered with a clear coat of lacquer.
