I want to apply paste/solution of pine sap on a surface,for that I have planned three methods. What would be the ideal for that
1) Melt it and prepare liquid form?
2)Increase plasticity by adding plasticizer, For this I need to know a good plasticizer
3) Dissolve in a solvent where after applied solvent will be evaporated,only resin will remain on surface? I need to know solvent
