Crc-656 is a great product. I like Boeshield T9 better though. I used to distribute both products for the marine industry. There were a couple comparison articles that found T-9 less expensive, leaves little residue (CRC leaves a residue that I don't like) and lasts longer. It was developed by Boeing for all aluminum alloys. It can be found at any marine store and probably Wal-Mart stores, too.
