I picked up a can of Renaissance Wax to use on my bronze coins but don't know the best way to apply it. I applied some to a modern cent with a soft cloth and it looks OK but I had to rub the wax in of course. Is there a method to it?
Very sparingly. Whilst the British Museum uses Renwax on some of their bronze artefacts, they don't use it on coins. A little will go a very long way.
I don't like Renwax for ancients or any coins for that matter. I bought some years ago and found I waxed over some BD I did not know was there. By the time I found it, it seemed the BD was accelerated under the wax. And then I had to find a way to completely remove the wax before I could treat the coin.
I've seen others post simular to Bing. I've never used it myself based on what I've read and heard. If you want to bring out the luster use a little verdicare or another oil based but safe for coin. I've had great luck with verdicare, even just to put some life on a dry looking bronze or silver.
I'm glad I asked people with more knowledge than me. I will keep it away from the coins and use it on my truck bumpers.
Alde, Renwax should only be used for steel or iron surfaces that do not have paint or any other type of finish. It's great on swords and armour
