There is no product or spray that can be applied over paint, stain or varnish that will saturate through it and absorb into the wood. Timbor is water based, as are all currently available wood treatments and will not penetrate paint. The surface of the wood has to be sanded bare, or the wood has to be drilled and pocket holes made every 6 square inches. If drilling pocket holes, this is a different process that might not be applicable to any wood except beams or posts.
