You can get the clear varnish here to match the NBQ colored spray cans. 400ml ensures that you can seal some canvases or other works of art. The clear varnish is available with either a matt or glossy finish (please select), so you can decide for yourself which suits your work better. Ideally, clear varnish should be applied in many thin layers. Each spray can is equipped with a universal skinny cap and can be used immediately. A modern cap system and fast drying times are features of the improved NBQ Slow.
