I'm Mark Abelson owner of Sure Shot Stain and Seal. I'm a retired Marine and started Sure Shot several years ago as a fence staining business in the DFW area. Fence, pergola, garage door etc. restoration led to Pressure Washing and some roof cleaning. There is a need but not a big demand for it my area however, I have done several using my 12v system. I need to continue to learn so I can market the service more aggressively. In return I might be able to help out any members here that are interested in adding outdoor wood restoration to their bag of tools.
