Here is the firewall painted with overspray about 1-2" down the firewall. I used PPG Lacquer mixed to match the original color since most of the car has the original paint.
Then I hand sprayed Omni Urethane black with a flattening agent to acheive about 50% gloss.
Looks pretty good without using a template. The paint is still drying at this point. I almost felt like a Norwood plant employee doing it!
