Question for anyone that's owned a Mossberg Mariner Shotgun

Per AI, not quite as good as cerakote, but still a damn good coating. If it is made for salt spray, it is bound to be pretty good. Depends on what you want to use the gun for….

I have a maverick 88 I spray painted white probably 25 years ago. It's been submerged in mud, stayed strapped to the rack of an old 4wheeler for months at a time, and been incredibly reliable.

Ive repainted it white once about 12 years ago because I wore through the acrylic hitting trees with the barrel. Soaked it in brake fluid for a month, pressure washed it, went right back to being beat up.

I said all this to say, save 600 bucks and just spray paint the maverick. It has an aluminum receiver. Coat the internals in moly Valvoline grease and it's gonna run.
