Reto has been an outstanding 'maker for many years! Lee if you bring this to Vegas you best bring a large bottle of Renaissance wax...as it will get drooled upon much.
No additions JJ just straight out of the bottle. Wipe it on (with a q-tip) keeping it moist until the blue fades out then rinse under hot water. Repeat until satisfied. Rubbing with a non abrasive (Pink Pearl type) eraser if needed then two coats of Renaissance wax blackened with lamp black...
