Norton Soft Touch Sanding Sponge - Ultra Fine
If you are looking to sand-polish a finish then this is the next step above the 500-600. This would mostly be used for smoothing out a topcoat before applying another coat or a wax finish or polish on top.
Coated on one side, these thin flexible sanding sponges are coated on closed cell foam to generate extremely consistent and uniformly fine scratch patterns necessary for applications such as sealer sanding and sanding between coats of primer or top coats.
