I've recently purchased a pair of J.A. Henckels razors that I am going to try and restore and get shave ready (will post pics when they are here, hopefully early this week). I was wondering if there is anything that may be done to the celluloid handles to help preserve them once they have been polished. I thought maybe someone here has tried it. Is there any coatings that you guys may have used during any of your restorations?
