Typically, a product like Meguiars One Step is an abrasive paste (to remove the oxidation) and will polish the surface, leaving a nice shine, but there is little to no "long lasting protection" like you'd find in a "follow up wax or surface protection"...

So, I'd recommend following the Meguiars One Step with a quality automotive finish wax or surface protection product...
