You appear to have painted using only longitudinal strokes with your brush - I would have thought tranverse strokes may trap gold better - although maybe I should have waited til after I watched the whole tape
@@pistonbrokeprospecting I seen on Internet to make your own paint get 1 part water and 2 parts plaster of Paris and mix until there no lumps. Then add 3 parts water based paint of your chosen colour and mix - DIY Chalkboard paint.
