Read an informative review of the fogger here.
As I went through here mods look amazing after a bit of polish, but tanks can look just as great and clean. I even hear it improves the taste and the vapor production. I need to try this on my Russian 91. This is Jos Olivo's fogger. You can see some of
Jose Olivo's mod collection here. The polish used is BlueMagic Metal Polish Cream.
