Diamond painting sealer for restoring shine: Hasi coating agent
Hasi Diamond Painting Coating Agent is a 247ml coating liquid for finished diamond paintings, tested in Korea. I applied it to two diamond paintings of Ariel and Aladdin that I made four years ago, and the shine seemed to come back right away while the silicone brush made it easy to spread evenly. Verdict: A great match for reviving dull diamond paintings.
