first what is the difference? which is better to use? and finally what are your recomendations on both? thanks

 

There are abrassive polishes and chemical polishes. Chemical polishes don't have any abrassives and they basically clean the paint bringing out more shine and reflection. Abrassive polishes will do what a chemical polish does plusthey can correct swirls and scratches too. Polishes also work great for removing oxidization and waterspots.

A wax will seal in and protect after you use the polish.

There are many polishes and waxes that you can get over the counter.

I carry some good polishes and waxes too. I use Optimum Poli Seal quite a bit, this is a paint cleaner,polish, and protectant all in one, you basically get the best of both worlds with this product.

 

Got my vote +1

 

Polish removes a very slight layer of your cearcot to remove light scratches and make it look all shiny. Waxes protect the paint and finish and you should to it every 1-3 months depending on the type you use.
