Under Dash and Floor Paint

[64impala]

What are you guys using as far as paint/undercoating for the inner floors, under the dash, and trunk. The whole inside of the car is bare metal and i was thinkin of either just undercoating over the bare metal and calling it done or going the extra mile and using KBS Rust Seal over the bare metal and then applying Monstaliner over that. Any thoughts? Thanks in advance

I took my floors down to bare metal as well. I used Por-15 and their Chassis black. I had previously used Por-15 on my engine block, firewall, rear-end and trans and had been very happy with it. Just have to get everything perfectly clean. Here is a few pics:
