cool, I like experimentation. FIRST, what effects are you trying to achieve?
Ive seen where a type of resin is allowed to"float" on top of a layer of thinner or solvent. The canvas is in the thinner and then soluble colors are daubed into the resin. (The thinner assures everything stays in solution)
Then the solvent is VERY SLOWLY withdrawn via the bottom and the resin /color is allowed to settle onto the canvas . The pattern achieved is like that of "marbling " on paper.
