Thanks for the advice. I visited yesterday a car detailing shop and they had a huge selection of wax products including SwissVax . We were discussing I want it to shine and protect a classic bike ...and was recommended in fact Dodo Juice, that comes in as little as 30ml samples for 6.95 euro. It has carnauba (or carnuba, I've read it both ways, not sure if one is more correct than the other) plus others, but to my purposes, that should work pretty well. I'll give a try and share the results.
