All 3 of our Artist Resins are used for top coating, the difference between them is thickness/viscosity. So the thicker the resin the thicker coating you will have. Original Artist Resin is our thickest, then Medium then Thin Viscosity is the thinnest. You also may want to try our Quick Coat sealer. Acrylics don't always repel resin, but it certainly can, especially if you've used silicone.
