Simicromo is good and has a good protection , neverdul is great for cleaning but doesnt protect that long , extremly easy to use , Flitz is great also and has a good protection to it , a little more time consuming then the neverdul but worth it , if your rims are bad then Mothers aluminium cleaner is great , use lots as the neverdul will clean up the excess mess you made with ease, these are my personal findings
