Thats good.
About paint, it may not work.. Please make a small test with the some part of the material if paint will interface with the resin or not. Sometimes when you mix unsuitable chemics, mix may became like " broken ", may became rubber or something else.. Better test before apply. May be resin needs acrylic based paints or totally opposite. Thats why its better to test with small amount for not loosing more bigger amount of the materials.
Have a nice weekend,
