I bought a used police trade-in 870 a few months back. It was set up as a less-lethal gun with orange furniture, including a Surefire forend. I pulled the forend off and sent it to Wilson's for their Remington Steal package and I've had it back for a month or so now. I want to paint over the orange parts of the forend and put it back on the 870. What's a good paint to use for this? I'm looking for flat black. I'm willing to go to Brownell's for the paint, but would just as soon use something from an auto parts store if that would work as well.
