i know this might seem crazy but i have noticed that the top of my table saw has recently gotten some scratches that run parallel to the blade,,,im assuming it came from using a sled,,now i know it just a saw and you will get battle scars on it as you use it but it is kinda annoying to me,,,does anyone know of a remedy to filling it in and maybe sanding over it or would that be a good idea,,,any help would be appreciated,,thank you
