While this was going on, I continued to periodically bathe the rest of the bowsprit in the end cut solution. It has so much copper in it now that it is as black as a railroad tie.
BTW - a word of caution to those who might want to do this - the end cut solution is pretty nasty stuff. If you get a drop on your hands, you will soon taste metal. Wear nitrile rubber gloves. Really.
Next week, I will start with the epoxy and microballoons, to smooth the surface in final preparation for paint.
