I've been having some issues with sealing patinas so I got these pigments:
Sadly after applying around 7/8 layers of spray varnish it's still really easy to damage the surface so I have to get something different. Right now I'm aiming for 2part car varnish because it acts very much like resin so it should be good... should be. I wonder if using sponges instead of a spray gun will work... Very annoying time for me -.-.
