I’ve used Venetian Shoe Cream and Saphir Renovateur on my Quoddy mocs with good results. I wished the Venetian came with a wider mouth, I’m almost toward the end of a 2 oz bottle and it’s hard the get the last of it out. Probably use an old tooth brush to get the remainder. The Saphir comes in a nice wide mouth container, I use a small brush to apply it to the leather. One thing I noticed is that the Saphir seems to darken the leather a shade or two. So if you are concerned about this, you may not want to use it.
Over the weekend I ordered a Montana Pitch Blend sampler. Their web site has a special going on for a kit which includes dressing, oil, soap, and the shipping for $15.00.
