GJS, you will be happy by using Meguiars products. I have used it for years without any problems. I use the Gold Class wax on my car, my parents Yukon and other vehicles, and even our snowmobiles. Also use the Meguiars Marine wax on our boat. If you have leather, get the Meguiars Gold Class Leather Cleaner/Conditioner spray. This will keep your leather looking new and smelling great for a long time.
I have heard Zaino is the best. But seriously, you better have all day and then some as it takes forever to apply and go through each step - 7 in all I believe. Me, I love to wax my car to keep it looking good. But at 1 application compared to 7 different applications I will be out driving showing it off before you are done with the second app.
