http://www.VideoJoeKnows.com Using a light for your sanding project....is a good idea. The light will show any imperfections on the wall, when you think you're done with your sanding project. Does it make that much of a difference for you to say you have to use a construction light every time you sand your walls? No, but if you are preparing your walls for a 'smooth wall finish' then "joe" would highly recommend that you try this technique. Using a light is amazing to where you thought you had sanded the walls perfectly then you shined a light on it & saw ah.....maybe I should do a little more sanding on my project. I won't tell anyone, but thanks alot "joe"! http://www.VideoJoeKnows.com
