What is your budget for this and is this DIY or a professional install? There are ceramic coatings (not wax) available that can be done yourself for $100 to professional coatings that cost $5000 and everywhere in between.
Edit: Just to add to this, how much time, energy, and learning are you will to devote to this? A wax or sealant for $15 will work for 2-4 weeks and will be easy to apply but taking the few extra steps and spending $100 will keep it looking nice for a year. Or if you want to go the full DIY ceramic coat, a full day of prep work will give you results for 3+ years.
