What would be a good paint to use to paint my firewall? I want to paint the entire firewall area including the upper cowel vent area. I'm debating about using POR15 as I still have almost a gallon of it and I like the way it looks. I would do the chassis coat also so the UV rays don't affect it. Here's a pic of my firewall as it sits now. I'm just in the process of grinding the welds down and cleaning it up. Any advice would be great. Thanks.
