Our water-based diamond spray works great for knives, tools and razors and it can be used on many different surfaces/substrates such as leather, balsa, basswood, denim and felt. We manufacture our diamond spray at our facility and can customize the concentration to some degree with particle sizes ranging from 3 micron to 1/10th micron. We offer them in 4 oz. spray bottles as well as quarts and gallons. This is a heavy concentration spray that works fast and produces excellent results.
We recommend using our spray on leather (smooth side) that has been lightly sanded with a medium grit sandpaper like 400 mesh and then wipe it down with alcohol. It can also be used on plain smooth leather.
