after all these years I've NEVER had an order for a black item. That is until my best customer(my wife) handed me a 1 1/4" belt and asked if I would make her a new one and black. I've been reading about vinegaroon here for what seems like years and wanted to let you all know what I found. With NO BLACK experience, I resorted to my old routine of mixing with Bicks #4. and guess what?
I mixed Bick's with USMC black, 50-50, put it on with a paper towel, painted on straight USMC black with the same towel, then a coat of straight Bick's with the paper towel. Took about 3 minutes to complete the entire belt, (no waiting between treatments) and I got a great looking belt that stayed black(not purple), didn't rub off, and felt totally smooth .
Hope this helps some of you in your quest for BLACK projects.
