If you have a brand new car, you won't need to use an abrasive polish. I would recommend using a non-abrasive polish to clean up the paint and prep it for the paint sealant and a coat of wax. The car's paint is already baked on from the factory so it is good to go.

We at Wolfgang Car Care have these products for you:

Non-Abrasive Polish: Wolfgang Paintwork Polish Enhancer
Wolfgang's prewax cleanser removes old waxes and sealants, light oxidation, and paint contamination to reveal deep color and gloss. Once you apply a wax or paint sealant, it will enhance the smooth, clean paint created by Wolfgang Paintwork Polish Enhancer.

Paint Sealant: Wolfgang Deep Gloss Paint Sealant 3.0
Wolfgang Deep Gloss Paint Sealant 3.0 features fortified polymer technology. Wolfgang's German Super Polymers are fortified with more dirt-repelling power to keep your vehicle cleaner and shinier, longer. Our enhanced super polymers have an amazing anti-static property that repels water, oil, dust, and road grime to provide unsurpassed paint protection. Your vehicle stays cleaner because foreign molecules literally slide off the clear polymer coating. Super polymers bond easily to automotive paint and form an extensive cross-linked polymer network. This clear shield eliminates surface tension so contaminants have no foothold on your vehicle. Will last about 1 year with consistent wax use on top.

Wax: Wolfgang Füzion Carnauba-Polymer Estate Wax
Wolfgang Füzion Estate Wax is a hand-crafted blend of carnauba wax, German Super Polymers, and proprietary ingredients that yield unequaled shine and protection. Our unique formula fuses the best attributes of carnauba wax and paint sealants to create the ultimate car wax. Wolfgang Fuzion Estate Wax has been enhanced with more glossifiers for a more intense wet look and improved slickness. Offers 6-8 months of protection.

You would clean up the paint, apply the paint sealant, and after a 12 hour cure time for the paint sealant you would apply a coat of wax. You get the best of both worlds when you use a paint sealant and wax. Paint sealant= protection / Wax= Depth and Shine. Hope this helps
