I use the standard stuff, then wipe it only with a "California Car Duster" If you get bugs try to remove them as quick as possible or lay a wet rag on them so they can be easily removed. As far as keeping the fine scratches out I use a product called "Fill n Glaze" It is designed for use on high end paints for removing swirl marks. This stuff is the best I have ever used and will make your night racing very "clear"
