Soluvar is a mineral spirit-based varnish that protects and resists dirt retention. It dries clear to a flexible, non-tacky, hard surface and protects colors from UV light damage while resisting discoloration - yellowing and fogging - caused by humidity, heat and UV. Depending on the substrate it allows surface moisture to pass through and breathe. It also allows for easy cleaning without fear of damaging the acrylic paint film and has excellent leveling properties.
