I sprayed the primer from an aerosol can as directed, then mixed the paint components in the right proportion and sprayed it too, exactly according to the directions. I used my painting coveralls, respirator and full eye cover.. It was tough getting my spray gun down into the valley at the bottom of the firewall, but it worked out well. I was very careful about overspray.
Then I sprayed on the clear coat from an aerosol can.
Here she is! You can see a small seam of paint color mismatch but it will be down behind the battery box and under the vent system. I just wanted it to be good enough to be a decent match and I'm happy with the way it came out.
