We have decided to use electric sanders to refinish the exterior of our cabin. It is not chinked inside or out, but we plan to do the outside at least.Can you tell us what tools and progression of grits you recommend for a successful exterior sanding job? Any other helpful hints that come to mind would also be welcomed. The cabin has a dark stain on it, but it is old and weathered and needs some tlc before we can chink it and stain it.Sanding it ourselves is the only option financially for us ri
