Detailing Firetrucks

[BLKONBLKONBLK]

So I do a lot of work in the fire house and spend a lot of time taking care of the trucks - obviously they are usually always clean and I have gotten the guys into using Collinite 845 which lasts for a long time given the rigs are garaged all the time

The question I have is has anyone spent time truly detailing a fire truck, I usually use 303 on the interior, and DP wheel cleaner and optimum tire shine on the wheels and tires -

I was planning on maybe using the SSR 2 from PB to buff out some of the swirls on the rig - assume its a hard paint -

Also was wondering what everyone would use on the chrome, aluminum wheels and a decent amount of diamond plating

Thanks for your input
