This item is a tool for use in model assembly. It does not require either cement or paint to complete or use.
A set of three plastic "bows" which you "string" with strips of sandpaper to create a useful flexible sanding tool, great for curves. Set includes the bows and three strips of pre-cut sandpaper in #400, #800, and #1200 grit, but of course you can cut and mount any sandpaper you want to use.
