Super Film micron abrasive film is ultra fine and guaranteed to give you a professional smooth finish on any project. This sanding film is for using AFTER the final varnish coat has been applied (3 coats and is totally dry). I recommend cutting it into smaller pieces. This will give you more (hehe) plus a smaller piece is much easier to work with. It can be used wet or dry. I prefer using it wet as it seems to glide over the surface easier. Gently sand, you will see only a white-ish powder, NO color should be disturbed. Wipe clean and dry. Try the touch test...it will be sooooo soft! Plus the sanding will lightly buff, creating a soft glow. This process only takes a minute and will step your project up to a higher level! You will be impressed at what a big difference this little process will make.
