I have been using Trewax for a number of years with good results. I find Johnsons too thin and too much of a harsh petroleum smell. I have also used a clear or neutral Saphir wax, a French brand marketed as shoe polish. It is a mixture of beeswax and carnauba, using turpentine for a solvent, smells rather good. I have read so much about Renaissance lately that I decided to give it a try and just got some in and gave it a quick application and am very pleased.
I just tried a comparison with my Saphir mirror gloss wax, and results are very close. the Renaissance buffed out a bit easier, but it was on different stocks with different oil finishes, so not a perfect comparison. Cost of the two waxes are similar as the Saphir is a premium product also.
I may have to give the Renaissance a try on my shoes.
