Charles LeClair, seen here, along with Northwest Trade Center Building Trades students Dwight Martell and Raven Kane, helps demonstrate the use of a Festool power sander at a unfinished house on the corner of Hudson and Federal streets in St. Albans City Tuesday, where the Building Trade students have been working recently. The German paint tool company, along with Prep to Finish painting trainers, filmed a promotional video Tuesday featuring the NWTC students with instructors Steve Wunsch and Mark Capsey. The promotional video for the sander will appear on Festool’s Facebook page, YouTube channel and Web site.
