Can I get some ideas on what brand shine or wax to use on classic cars? And how often to use?

By far the best stuff I've ever used is this. Pure carnauba no cleaners. I use it on my original paint stuff as well as the 914. I believe it's an East Coast product, but I purchased it on eBay. I used to be an exclusive Mother's product user until Gliptone shined up my life. LOL I use it about once every 6 months. Smells good too.
