Very nice spine work on that razor. Speaking from my own experience; here's the good news: If you rub lightly for a short amount of time, checking as you go along with a soft cloth and Maas/Flitz over the gold wash, it won't come off. Here's the bad news: It will START to take it off right away in that the wash will lighten. The more you rub, the more it will fade. If you kept rubbing and rubbing, bye bye gold wash.
